Well, my brother did not get sick last night, but that's certainly not saying he wont.
Ugh, according to him, this boy in his class, Sam, threw up this afternoon. He happens to sit next to Sam in just about every class. Sam was also in the same room as me and my brother yesterday for a few minutes. He had his piano lesson after mine and my brother's. I don't think any physical contact happened, but still.
And also, my brother washes his hands only when he takes a shower, which is about once a weeks at the most, but I'd not be surprised if he put gloves on his hands or something to make sure they didn't get clean. I'd never dare ask my brother to wash his hands, because if I did, he'd probably just lick them and stick them in his mouth.
