Sadly, I can relate: I had my 5 year old at Kennedy Space Center a couple of months ago. My sister was with us, and he was play punching her all day. We get on an elevator, my Son rears back, and whack! Right in her hiney…except it wasn’t my Sister who was in front of him.
Luckily, the lady had a great sense of humor and laughed…
And I thought the strip was just about Calvin trying to get out of doing homework?!
