Two moments that occurred within an hour of each other with my only-just-two-years-old child.
1) Me, after preparing dinner for the family (we switched to doing dinner together a few weeks ago and it's been mostly successful so far): "Little Miss Cognac, come help me set the table please" - a task she has been helping with for a while and is more than capable of understand and completing* (with supervision).
Little Miss Cognac, playing in the lounge room with Mama but I'm the midst of packing away: "TWO MINUTES PAPA, TWO MINUTES"
Me:

2) Sitting at the dinner table I "forget" that I have a large piece of spinach sticking out of my mouth. Little Miss Cognac, turning to Mama, completely deadpan: "Funny Papa", returns to trying to spear her food with her fork.
She's 2, people, 2. I thought there was supposed to be a good few years left before we started getting this level of sass...
