Hi guyz, when i came home today after work, my lil sis said the milkshake in the fridge at home had an unusual sour taste to it, but she already had swallowed it but didn't drink more. I tasted it, it was really gross. I didnt' ingest it. I'm a lil worried that my sis will be sick coz milk shake is made of milk..[img]smileys/smilies_12.gif[/img]What are the chances? It wouldn't expire till Sept 14, 2006. I don't know why it tastes like that. Edited by: bigemet
