Brain Covers

A while back Will and I were driving home from church and he was telling a very detailed memory that I didn't share.  I commented on how well he could remember and that when you get older, sometimes your memories sneak out. 

He replied very matter of factually, "yeah, I know, its because I have brain covers." 

Me- Really?  Where did you get them?

Will-  I was just walking around and I found them laying on the ground.

Me-  Do they go over your ears or something? 

Will- No, they go right here.  (pointing to his temples)

Me-  You know, I forget a lot, do you think you could find another pair for me?

Will-  I did, but they were made our of cement and I couldn't carry them.  Mom, my memories can't sneak out.  They don't have arms, they are just words. 

     He will still regularly comment on his brain covers and when we are learning something challenging and he is able to figure it out, he refers to his "ant home brain."  Your guess is as good as mine.
