We talked about his daughter for about 15 minutes. She was a good student and so I really had no reason to keep him there talking for much longer, which was frustrating, I wanted to spend a lot longer talking so I did something I am not proud of. I told him his daughter did have some behavioural problems in my lessons and id like to talk to him a bit more about it, he agreed and said he would happily wait until the end to talk to me about them. It was the end of the evening and after speaking to ten more parents I was frazzled and did not remember I had a parent waiting for me. His name was Brian and we talked a while more about his daughter as my guilt over getting him to stay meant I was back tracking and hoping he would leave.
