Dyslexic Painters

We're painting the walls in my daughters room two different contrasting colors. Before we started painting the first color we had to make the decision which walls would we paint with Color A and which walls would we paint with Color B (she has a weirdly angled room with more than just four walls.) Having arrived at our decision we began 'cutting-in' with Color A and BOTH of us almost immediately began painting the wrong walls, the wrong color because THAT'S how short our attention span is.
