"Get out of my way!"

I was in his way when he was on the trike today. My response: "Excuse me?!" I was in disbelief that he'd actually say that... and from who or where? After my reaction he says, "Excuse me, please." That's more like it! He has an attitude when he says things sometimes that drive us crazy. Where did it come from? Ugh. Two other annoying phrases: "I yit!" Translation: I did! Or, I did it! It's his way of telling us he's done it already. Or he says, "Imit!" Translation: I am! Or I am doing it!
