Tasty germs

My eight-year-old son and i were shopping at the store. He had a package of Skittles that he was eating, and he kept dropping them on the floor. I tried not to notice as *cringe* he picked them back up and ate them. But when he dropped a whole bunch on the ground and started to pick them all up, I asked, "Don't you think that's gross? There's germs all over those!" He answered thoughtfully, "Yeah..but you can't really taste them."
