Meta...what?

I walked downstairs on Saturday night to catch the tail end of a brother-on-brother argument.

I hear B look at his younger brother and say, "I'm going to kill you if you do that again..."

Then, he spots me coming down the stairs and he adds, in a louder voice to make sure I can hear...

"I'm speaking metaphorically of course..."

Guess he's learning SOMETHING at school...
