context: When I was young, my mom had an obsession with painting the walls of our house. As soon as she finished painting one room, she would start on another. We were in this never ending flux of wall colors. Her most ambitious project was painting her bedroom in an unconventional way. Instead of using a roller and painting the walls a solid color, she would dab a rag in the pan of paint and repeatedly press it against the wall, creating a unique textured look. The problem was, her bedroom was huge, so this took months and enlisted the help of me and my siblings. The first time I tried it, I did all of the dabs in a really uniform way, so each looked like the other. This was not how she had painted the rest of the wall, and so my section stood out and looked very different from the rest. She didn't paint over it or anything, so for the remainder of the time that we spent in that house, that section of wall looked completely wrong and out of place.
question: When did they finish painting the wall?
