We're (me and my brother) staying overnight at the house of this little kid we've known for years and I forgot my pajamas and my brother is super queasy and sick all of a sudden. I'm worried because we went to McDonald's for dinner and he got one of the new burgers, and you know how there was a parasite in the salads? What if it got in the burger? I'm a habitual worrier (thank you Thomas Sanders for that term) and now I'm super worried about why he's sick.

He may be taller than me and is able to pick me up with ease but he's still my little brother and I hate it when he gets sick.
