A/N: Okay, I didn't want this to sound too cheesy mush-gushy, lovey-dovey, and I hope this isn't too OOC for them but since it's almost Valentines Day I wanted to do something with a romantic B/R. I believe that Barney & Robin have their own traditions in their relationship that nobody knows about but them so I wanted to do something to show that they can be romantic but in small doses. They love each other enough to sometimes not say things out loud but they are also very private loners so I think this fic works for them.

Description: The meaning behind any message is from the heart rather it's a modern day text message, a leave your message after the beep kind of message or in this case a small simple message on a post-it note. Big gestures are lame in this world but the small gestures are from the heart and ever since Barney and Robin started become more than just friends these little messages are their way of saying I love you. They don't say it out loud but they know it's true. For the rest of their lives this little tradition never became old or dull

Enjoy, happy Valentines Day!

It happened by incident, it wasn't supposed to have been said especially in the early stages of their dating relationship. But, it happened and once it happened it continued to be a thing they both liked doing for each other. It wasn't anything big like buying your significant other a car or any kind of romantic gesture Ted ever did for a girl. This was small, a small gesture that told them both that they love each other. The small gesture had become grander/bigger than any big romantic gesture there is. No, this was big for them, neither loved big romantic gestures and at one point just plain hated them. But, ever since they fell in love those little notes they leave for one another each morning or each night or whenever they feel like leaving a message on a tiny piece of paper it never gets too romantic or cheesy. It's just simple and sweet so that tradition happened to continue into their marriage.

The little post-it notes became their own inside joke that became to mean something more. A big romantic gesture that meant more to them than anything else. Over the years, even when they weren't together romantically they still left a little note that expressed that the other one still cared.

Robin, I have to go to work but I hope we're still on for dinner later.

Love you: Barney

Oh, P.S. Was that too soon to say the L word? I'm so stupid sorry didn't mean to say that so fast and only three weeks into seeing each other.

He at first didn't mean to say that and it was a bit too soon to say something like that especially for someone like Barney Stinson who never says that unless it's to his mother, brother, friends or the exception. In this case the exception is Robin. But, it wasn't too soon because in those three short weeks after their talk and make out session in the hospital they had both been secretly believing that they are in can take back the Love You in the post-it but it did make Robin realize something that she hadn't yet realized or understood.

She too loves Barney, she was always afraid of saying I love you to someone so quickly cause it meant that the relationship might not last longer than a week. But, with Barney it seems right to say I love you to him and mean it even if it's on a post-it. Which, now years later still reminds her of her love for her husband and the amount of honesty and trust and love that those little pieces of paper represents even when they aren't together in someway.

No, it isn't too soon I love you too.

Robin

She had wrote this reply the following morning before she went off to work. Robin was never one to do cheesy romantic stuff like saying I love you on post-its so soon into a relationship but that summer was the best summer of her life and she will always cherish those times she spent with Barney hiding being together from their friends. She's still shocked that nobody actually caught them.

She remembers one early morning when Barney had stayed a bit too long at Robin's apartment and left before dawn and before Ted wakes up to catch Barney sneaking out her bedroom. But, this particular time was a close one but it made for a funny post-it message when Robin went over to his place the next day.

"Barney, I'm here are you home yet?" Barney had given Robin a key to his apartment for emergencies but soon the apartment became a home, a place she can call her second home which surprisingly Barney didn't mind.

Barney wasn't home yet but sitting on the coffee table was a note from Barney.

I think I almost got caught this morning;

Talk more when I get back

Love you

Barney came home fifteen minutes later where he was greeted by an almost naked Robin.

"Welcome home, sorry about not kissing you goodbye this morning. I can't believe Ted almost saw you leaving." Robin says in a sexy low seductive voice walking over to Barney standing near the front door.

"How was your day?" She says places both of her hands on both lapels of his suit jacket.

"Wow, you're ready to go aren't you?" Barney says with a laugh, damn God did something right when this wonderful woman came into his life. He would have never thought that being committed to someone was this much fun, it's exciting to not only spend time with Robin but to be having so much amazing earth shaking sex was something most men dream about and some only get to accomplish in a lifetime.

"Always." She says taking off his jacket and the unbuttoning the top of his dress shirt.

That night was legendary and that summer was amazing. They didn't realize it then, but they were falling in love, neither said anything at the time and neither would even admit it to themselves but they were. That summer brought out a whole new side to both of them, Robin had been a sex kitten but also came to discover a new meaning to her life and actually embraced love. For once in her life she was in a relationship that didn't make her feel less than, she was having fun with her best friend and having the best sex of her life. And, Barney he didn't understand what being cared for and committed to someone meant, this had been too wonderful for him but it also opened him up to commitment that is loving from both sides of the relationship. but he too embraced the feeling of being in a real committed relationship that didn't seem all that bad. They admit that both are terrible at relationships but it seems so easy and fun being together, they never felt so alive before.

By the end of the summer those post-its had become something they both did to tell the other one that they are loved. Even years later when she looked at the box of things from their relationship she truly realized and understood what being in love really meant.

Happiness...
