We were driving over to M.E.'s school for a dinner and an open house. It's a short drive, less than 10 minutes. About halfway there I hear rip, thunk, rip thunk from behind me.
"Nate, did Nicky take off his shoes?"
"Nicky, don't you dare take off your socks."
After a minute of silence...
"Na, na, na..."
"Nate, did Nicky take off his socks?"
"Yep, and he's saying na na na boo boo."
Sure enough, in the rearview mirror, I see that Nicky has his thumbs in his ears, waggling his fingers singing "na, na, na"
I did the only thing I could, laughed.
