20 years after the leaving of Hogwarts, Harry is sending his kids off for another year at the School for Witchcraft and Wizardry, when he sees Draco staring down at him, when Draco starts walking down to him as the train pulls away from the station. "Hello Potter" Draco says to harry with a small smirk and his usual voice throughout their years of Hogwarts, "Hello Malfoy" Harry replies in such a rude agnostic tone.
They both separate and allow the crowd of parents to rush between them while they both start talking small talk between them, their wives walk up to them and start pushing them away from each other at the end of their conversation Draco gives Harry his phone number and insists that harry is to call him later so they can do a catch up day on their years away from Hogwarts and how their lives have panned out and their marriages are.
Three hours later…
Draco's Point of View
Draco feels his phone buzzing in his pocket, staring at the number wondering who it is, it just rings out, he gets a message a minute later from the strange number that reads;
"Hey Draco. You said I should call and I thought now would be a good time as I am off to work. I hope you can call me back shortly, From Harry P." Malfoy then decides to save the number to be a work colleague so nobody knows who it really is.
He quickly saves the contact and rings Harry back. "Hey Potter, Thanks for ringing me, sorry I didn't pick up the first time didn't know it was you until I got the message" Draco states in a nice, calm tone.
"That's alright" Harry says in understanding as he would have done the same thing.
Small talk happened and a date was set for them to catch up over coffee. "What am I doing" Draco's mind starts rambling on because in school he hated Harry from the first minute they got into the school mess hall to decide what house they were going to go into, but why all of a sudden some deep connection with him.
Harry's Point of View
Harry pulls out his phone to dial the number that Draco gave him to call him on. Harry rings and it just rings out. Harry confused at this decided to send Draco a message stating that it was him trying to call and to say that if he gets a chance to call him back. A few minutes later Harry's phone rings, all that is running through his mind at the time was "this is Draco, I wonder what our conversation is…" He quickly answers his phone and cuts off his mind in the middle of a thought. Conversation ends about 5 minutes later with a coffee day set.
Two days Later..
Harry wakes up to check the time, it is only 06:00 "Okay so I have work first at 09:00 and then Coffee with Draco at 14:00 on my lunch break from work. I wonder where we are meeting for coffee, Draco wouldn't want it to be in public as people think we still hate each other but it would be nice to meet close to my work so I can get back quickly without having to use magic as I work with muggles." This runs through Harry's mind as he gets up without waking Ginny. Suddenly Harry's phone rings, he checks the caller ID and it is Draco.
So Harry quickly picks up the telephone call. "Hello" Harry states calmly. "Hey Harry it is Draco, I know I haven't set a place for coffee so I was wondering if we could do it down in the Leaky Cauldron? Do you think you can get there and back on your lunch break and still have time for coffee?" Draco asks quickly and quietly to not disturb Astoria. "Yeah I can do that, we are wizards after all" Harry says chuckling to himself. "Okay sweet and yeah I know but I know you work with muggles that is why I asked." Draco says abruptly. "Yeah that's all good. Alright I will see you then, I have to get Ginny up for work." Harry says as he hangs up the phone. "Who was that Harry?" Ginny asks as she walks into the kitchen. "Just a work colleague who isn't coming into work today so I have to work through my lunch break and maybe a little bit after, don't worry I will ring you when I am on my way home." Harry says as he walks out the door to go to work.
