go to the card store, buy like 50 cards (all kinds) and mail them to all the girls you know (which from the pic thread, looks like a decent number of decent girls). don't say 'i'm lonely' because that sounds pathetic. just say, was thinking of you today or something like that. wait for a couple of days. your fan mail comes back. and, voila' you are not AS lonely.
then, work up your bravery...and answer the cards in the order that they were received by calling them up one by one. get out your appointment book and fill it up with 'cheap dates.' not cheap dates, but cheap dates. you know. go to a free concert, go for a walk, horseback riding, swimming, etc.
then, at the end of the summer, you won't go back to school all depressed and kill yourself in the first week due to negleting your social side.
