I went to school with my backpack, and when I opened the front pocket, a colony of ants swarmed inside... Apparently, I left my bag open (with bread crumbs inside) on the floor. So I spent like 3 hours shaking them out, whilst working and studying. Every time I thought I got them all, there would be a whole group of ants still hiding in the cracks. Man, that was hell. For the rest of the day, I pretty much itched all my skin cells off. In the end, I threw away that backpack and used another one. *sigh*
