And where are the girls?

A few weeks ago, actually, late October, i had asked R to help me bring the futon over to my apartment. I did not have anywhere to sit. In classic R fashion, he said yes but never followed up. My b-day was approaching and I wanted to have a place to sit on my b-day. So on Saturday I called and asked very politely when he thought he may have some time to bring the futon over. To my surprise he said "I can do it right now". OK, I said, not believing my luck. An hour or so later he showed up. I opened the door and he came in with parts of the futon. He went back to the car and brought the rest. I asked him when he thought we could other things, like bookshelves, and we got into some other conversation I cannot remember. Then he suddenly said "Oh, I should go, I have people coming over for dinner at 6. This made me wonder where he had taken the girls. I asked "where are the girls?" "At home" he said. At home by themselves? I said. "Don't start giving me your perfect parent shit, ok? Yes, they are at home, so what!!!" and went on with his yelling, to what I said, well, you should go because they are by themselves. And he left. Knowing that he does not have a sense of risk, that he does not pay attention and that he feels perfectly comfortable doing things that I don't is not an easy part of having 50-50 time with our daughters.
