Tiny teen

Henry is absolutely the most contrary boy in the world.  If I so much as suggest something, he'll automatically take the other side.  Yesterday in the car, he was trying to wipe his nose on a plastic bag.  I handed him a kleenex, and he tossed it on the floor.  This morning, he forgot he had his backpack on and tried to put his sweatshirt on over the top.  When I reminded him to take the backpack off first, he asserted that he wanted to wear it that way.    I guess it's his job to be declaring independence every day, but for pete's sake!  It wears me out.  And it makes me a bit sad, because he rejects everything I try to do for him (the cookie cutters I brought him from Texas, and the winter coat I bought yesterday, after carefully asking for his color preferences and so on).  He doesn't want me to be upset, but on the other hand he doesn't want to do what I clearly want him to do, either, on principle. Maybe I need to consult some books on parenting teenagers?
