Soo my cl was igned garbage duty... (please read)?

because several people played a prank on the principal & she... didnt like it. and she tried to find out who did it, and all she knows is that its from our cl, so our entire cl is igned to take out garbage/help the janitors untill we "fess up" aaanywayys, there is one guy who (is really nice by the way) and weve talked quite a few times, but the past couple days he has taken my bags of trash out for no obvious reason (its in the seventies, so its nice) i just wondered if maybe he likes me? because ive had a crush on him for a while, but i never got a chance to really talk to him & get to know him till now. should i go for it?
