Input: Text: it didn't happen today but still...pretty gross fuck up
so i used to live with my boyfriend's parents and brother and sister for about a year. i had this hideous long tye dye shirt that i wore as pajamas but then decided it was too hideous to wear even to bed. we then used it to clean up after our lovemaking sessions. about a month after that we decide to throw out some old clothes and that shirt was on top of the pile which we had outside the door in a bag ready to throw away. i didn't notice that particular thing missing when i took it out to throw away but the next day here comes his sister wearing that shirt only cropped to be more "fashionable". she goes on to tell me she hopes i'm not angry that she took it and all i can do is tell her it's not a problem. i hope she doesn't go to any black light parties....
