Today, I came upon RU sitting on the floor, carefully ripping up a long cardboard tube the kids had been playing with earlier.
“What are you doing?”
“I’m tearing this up. So that we can’t use it.”
“Yeeeessssssssss, I see that. Why are you tearing it up so that you can’t use it?”
“So there won’t be a problem if my sister and I both want to use it at the same time. Now we can’t.”
Way to head that off at the pass!
