An Artistic Depiction

On Tuesday afternoon, Jackson and I went to our friends' house for a little while.  While we were there, something happened to Jackson.  By looking at the picture he drew Wednesday morning, can you tell what happened?

There were three people jumping on the trampoline.  Jackson landed on the springs on his bum, and he started crying (thus, the "wahhhhhhh" at the top of the page.  I LOVE that he had to draw the picture yesterday.  I have to admit that it was sad yesterday to watch him desperately want to jump on the trampoline, but his tailbone was so sore that it was painful for him.  I couldn't tell what was more torturous, landing on his bum or not being able to jump on the trampoline because of the soreness.
