In an attempt to both speak Dutch more because apparently my pronunciation is so shit that my "accent makes it really hard to understand you" AND in an attempt at teaching Jonas by exposure and osmosis, I have taken to responding to things or saying random things in Dutch and letting Jonas figure out from context what I just said.
Lately, every time I have to do something I don't want to do or, you know, stand up and walk across a room or something, I have taken to saying "Dat kan niet. Ik vind het te moeilijk." (No, I can't. I find it too difficult.) in the most obnoxious tone of voice possible. I have no idea if Jonas is amused, but I certainly am.
