I now usually do things a bit more secretly. Not that the other person wouldnt pick up on it, but i try to focus on getting to be good friends, and with that, i try to ask a lot of questions to see if they would be good material. Eventually i get my answers and save myself a lot of "i like u's" rejected. Of course, if too many questions get answered positively, well, by then she would have hopefully long picked up on my thoughts and usually something like a friend comes along who has noticed we have gotten a bit too close, and does the "hey, so do u like soandso?"
lol, last year im not sure if even one crush that a girl had didnt get spoken to the other girls i worked with. They seemed to have a talking issue, go figure.
As for crazy stuff i have done to show a crush i liked her, one time in high school this girl i liked was sick and didnt have anyone to take her homework to her. I volunteered (dont ask how i got the work, i cant even remember myself), and then i road the bus home that she normally took, and got dropped off at a nearby trailer park. I then walked up to her door, gave her her work (to which she replied "where's your ride?" and im thinking i probably lied at the moment, lol), and then after she said thanks, i left and began to walk the several miles it would have taken to get home. Thankfully some old lady picked me up partway and dropped me off. heh.
