Just this second, I noticed a small family out on the Arts Quad at the Big Red School on the Hill. A young Mom and Dad, probably both grad students, were throwing a bouncy rubber ball back and forth while Little Baby Girl (who can't be more than a year old) was reading her little baby book. Mom miscalculated her throw and the ball bounced off of Little Baby Girl's head.
I couldn't hear anything from inside the library cafe, but you could tell the baby was screaming. Mom and Dad didn't seem too worried, though. In the time it took me to write this, Little Baby Girl was hugged and soothed, and is now back up and around, enjoying the sunshine and the grass, almost like nothing ever happened.
