OR...it could have been one of those ironic t-shirts that you can get at Urban Outfitters, Abercrombie & Fitch or Old Navy...the ones that say "Bob's Surf Shop" or something...I have a few of those myself but have never been to or lived in the place on the shirt. that's what the shirt looked like to me when I saw it. she could have picked it up at a homeless shelter or from a college clothing drive or something.
That's why I don't give too much credence to what vics are wearing usually...because they could always be donated clothes. and to add to this actually...I was in Colorado a few months ago when I saw a young man wearing a t-shirt that said "Waltham Boys and Girls Club". I jumped up and asked him if he was from Massachusetts, because Waltham is the next town over from mine, and I know that Boys and Girls Club. He said no, he had no idea where Waltham even was, he had picked it up in a bin at a Salvation Army as part of a halloween costume. so, you never know where some shirt you donated years ago will end up. I'm pretty sure there's a homeless person somewhere wearing an old swimteam t-shirt of mine.
also, a friend of mine who went to college in SC had his fraternity sweatshirt stolen out of a dryer at a laundromat in town. a week later, he sees this homeless lady walking down the street wearing a "Sigma Ki Ep" sweatshirt with HIS name on it! he got out and made her give it back. so...she could have also stolen clothes from the laundromat. I've had stuff stolen before.
so again, when it comes to the t-shirt, don't put all your eggs in that basket, cuz you never know where she got it from.
