There's more to this bad day?

With all the ceremonies and events today, my cell phone was off most of the day. I didn't even have it with me during graduation ceremony--since I couldn't answer it up on stage, what would be the point of carrying it? My S.O. can cover for me if there is any emergency with the kids.

Turns out, there was an emergency!  Son got himself a (mild) concussion!

It wasn't from sports, as I had always feared.  Not even from horsing around. 

The 5th graders had read a book about a blind person.  Then they all put on blindfolds and walked around the playground to gain some insight into what it is like to be blind. 

Apparently my son wouldn't last a day without sight.  He walked into the corner of a brick wall hard enough to cause a concussion.

He'll be OK.  Turns out there's not much you can do.  But I still feel guilty--doesn't it figure that the one day I turn my cell phone off for longer than a 75-minute class, one of the kids has an emergency!
