Yes: This word can mean everything from a call about getting the job you interviewed for to your excitement over something so amazing you just have to shout "yes" because you want the whole world to hear how happy you are. Yes, can also mean when someone proposes to you out of the blue and knowing that this guy on one knee in front of you is the only guy you really and truly want to be with. Saying, yes to a proposal from the love of your life, the guy of your dreams, the only person you ever dreamed of having a life with and spending the rest of your life with that person.
"Yes" When Robin said that little word she meant it. At first she was so angry and confused by Barney's play The Robin but once she saw him in front of her holding out this gorgeous diamond ring on one knee her attitude and expression changed.
She said yes, not because she thought she had to but because she really loves this man with everything she has. She can put up with his crazy antics, his Playbook acts, his womanizing (to an surtain extent), his loyalty to his friends. She can think that all of the things she didn't like about Barney is crazy and insane and competely nuts but she loves it all. She, loves the man for who he is even though sometimes she wants to ring his cute neck. But, the main reason why she said yes is because she's tired. Tired of running, tired of hiding, tired of getting drunk and crying over him under tables, tired of being lonely, tired of being sad, tired of letting herself down by constantly hurting him. She's tired of it all, so when he's down on his knee holding out this ring asking to marry him all of her fears of him not being man enough to make a full commitment to her.
So, Barney Stinson proposed after all of this time being so against commitment and marriage but he proposed. Robin couldn't believe it, she's only dreamt of being with him again and running from what she really wanted and now he's fully commited to her it was her dreams coming true. For once in her life she made the right decision and said yes cause all she ever wanted is to be back in the only person's arms she's ever felt safe and happy in. Kissing him again, holding him again, his arms around her where they belong looking out in the night sky with the snow gently falling down upon them. It was getting colder but the warmth of being in Barney's arms again made all the cold that was coming go away.
