So, I had this dream last night...
My son says to me, "(Someone) and me are going out."
"(Someone) and I," I reply.
"It's (someone) and I," I tell him.
"Why not (someone) and me?"
I explain to him, "Whenever you're in doubt, just remove the part before I or Me. 'Me are going out' sounds stupid. The goal with grammar is to not sound stupid. Sounding stupid is a bad thing. It makes you appear stupid. In fact, it makes you stupid be default."
Which is when I woke up, thinking, "So don't be such a fucking retard, kid."
Yep, leave it to me to mix dreams of parenthood with a diatribe on grammar...
