Can you give me hypothesis about what's going on?

I would say that "long" kiss sure was NOT a quick "good bye" peck as it should have been. AND, IF that was coming from her father? That was NOT a "normal' kiss he should have been giving her! I don't know if this was coming from her "cousin" or her "father" after reading over your post a couple times. But I'd say regardless of who it was, it wasn't your "normal" good buy peck such as it should have been by "my standards". Good luck!^
