Trees don't have arms so they can't hug you back. They don't feel pain or sorrow, they can't scream, and are by all accounts completely incapable of consolation. They are, however, majestic organisms who give us shade (well, we more or less TAKE the shade from them, what're they gonna do, withhold the shade or something?) and cleanse the air of pollutants. We, in return, cut them down to make paper which we then print pictures of chicks in bikinis on them. They perform all varieties of valuable services, I guess.
