There's this guy I've dated but the relationship never really worked out. Recently, I've noticed that he looks at me sometimes and when I pass by him in the hallway he'll talk to me about something unimmportant. It's not enough for me to feel like he still likes me, but sometimes I get the feeling he wants to get back with me.
I've also noticed that he has changed routes to his next class so that our path cross in between second and third period. He used to take a different way, though I'd see him walking in the distance, but now he passes directly in front of me.
