As the parent of two small children, I sometimes wonder if they have made a pact to see how far they can push me. One will start crying, so the second starts yelling. One will fall over and cry, so the second flops down and starts howling.
Dot will wait until I'm not in the room and put a toy hammer through a window.
Marcus will wait until the window is repaired and then brace against it with his teeny little backside (to shove the couch out) until the window comes out as the glue hadn't set. Five minutes after the lightning storm starts.
I finished the blanket for my customer.
