Either blow it all on a PC, or buy a couple of smaller things (namely, a PS3+games, animu figs to add to my collection, and go out to an (extremely) fancy restaurant w/ family I guess)
How would you react if someone of a different sexual orientation asked you out? (for example if you're a straight guy than it'd be a guy asking; if you were gay than I'd be a girl asking you out, and so on. If you're a bisexual, than I guess this doesn't apply to you)
