Upon hearing squabbling in Tyler's room, I went to investigate.
Tyler: "Hope's pushing cars on the top of my garage."
Me: "Tyler, Hope cannot hurt your garage."
Tyler: "But, Mom, she'll take the paint off it."
Me: "She can't do that, besides it's already been colored on."
Tyler: "I didn't do it."
Me: "I know you didn't do all of it."
Tyler: "Well, an(unnamed cousin) did the pink, and I certainly didn't enjoy that."
Moral, you can color on a my son's toys. Just don't use pink.
