Girlfriends are easy.
I don't have one, "EASY then!" you might think, but alas.. I have this friend, who is a girl, but we have nothing romantic going on, or, a little perhaps, but nothing in the realm of relationship, even though I am working on that. She is probably the hardest girl I have ever tried to get to.
Anyway, she insists on giving me a Christmas present, and thus I feel compelled to give one in return. So what the hell do you give to a girl you like, but do not want to potentially ruin anything by being too 'aggressive' with the signals you send?
