Racing in bed

I hate hospitals, but today the boy had a scheduled operation to help his bunged up ears. The worst of it is watching him slip out of consciousness just after the "magic milk" goes into his bloodstream. Then the wait.
But 2 hours later and he is recklessly racing cars in his bed - the hi tech, creaky plastic hospital tv (with squeaky audio) pushed aside thanks to the wondrous tablet we brought with us.
