Absolutely everything. "Look at those fish DS! Aren't they big? (Massive....) "they're NOT big. They're little"
Shall we get some grapes? "No. I don't like them" (He does)
Be careful of the oven, it's hot "it's not hot, it's cold"
And so on. It's driving me bloody potty to be honest. How do I deal with it? Just ignore it (and therefore never speak to him? )
