The following conversation took place yesterday when I brought Rose to my mom's 2nd grade classroom. We'll call the 8 year old girl "Sally".
Grandma-Does anybody have any more questions about Rose?
Sally-Yeah, what's that on her head?
Me-Rose is learning how to crawl and walk, she bumps her head all day.
Sally-Is that why her head is so big?
Me-(Stiffling laughter) Oh no, she just has a really big head.
