When talking to someone for the first time in A long time, you should remember a few things.
For one, they will probably talk about when you last saw them. That’s pretty typical.
Further, they might make some mention of some prior shenanigans.
If this person wants to talk to you, they want to talk to you. That’s not always the case.
They’re not stuck in the past, but they don’t know anything about you and don’t have any more material with you (like a stand up comedian). But they’re bothering to try.
They’re probably talking about the past because that is the only thing they have with you. Give them some more material. Let them make you laugh.
What would happen if you both gave each other the present?
