Last night during dinner:
My Son:
"Hey, I forgot to tell you. This morning in the subway station, a rat fell from the ceiling right onto the platform, flipped over and ran off!"

So what do I do with that information? Do I have to stare up as well as down when I stand waiting for the train from now on?
Oh why did he not forget to tell me?
