I need advice

He was just being nice, being nice is contagious, try it! I watch the film Pay it forward, id been doing that for years!

Probably just being nice. Don't over-think it.

He was just being nice, just accept the favor and go on with your life... ;) because he was an old friend... if you don't want that to be just a nice gesture, go and ask him if he would be interested to go out with you, if you are interested of course too or if he wants to be friends and hang around sometimes, because the world need more friendship not more yoga and coffee haha enjoy your life as it unfolds be good and be safe and don't exploit his good gesture all the time now haha

Where I'm from, it's not all too unusual to pay for a friend's bill. Especially if you haven't seen that friend in a while. I think he's really just happy to see a familiar face around. :)

I think he was just being nice. You and him share a bond (a shared history so to speak) and he was acknowledging it. Perhaps he feels something more, I think he definitely likes you as a person. I think it was an act of solidarity for someone he likes.

Never overlook that there are kind people in the world ... For all you know he may have been repaying some small kindness that you showed him

Was your drink extra creamy?

I think it was something else

Maybe he's still crazy

He was being nice.
