He's still at it

I am sitting in the living room minding my own business when...

Dorian: (in the dining room) Shit!

Me: groaning inwardly, concerned I have uttered this under my breath lately and he has picked up on it or something

D: Shit!

M: What did you say?

D: Shit. I'm spelling words and I made the word "shit".

I go out to investigate and he's using blocks to make letters. He then went on to spell "toot" and "rut" and, mysteriously, "hrut". Boy's got a knack for the scatological, though.
