you and peter were at a time when the class was free for the last two periods, it was a cold autumn day and you were in school - it was rainy and cold outside... but the vibe was very nice, the classroom was warm and everyone was talking to each other and so it was a nice atmosphere.

you and peter were in a different relationship -you can't call it close friends, it can't be called boyfriend, either. We can call it situationship.
