This has happened to me, with one of my sons actually. He and his family are very busy with school, work, and raising a two year old...so when they needed to reschedule a visit, I was okay with that. I was not okay with not knowing about it being rescheduled until I called him on the day I thought they were going to be here.

It wasn't intentional on his part, he is an amazing son, but after a few times of this...I did have a conversation with him about it. Told him that these no shows were not acceptable. Asked him how it would make him feel if I promised to watch my grandson for him one day, but when they brought him over, I told them that something came up where I couldn't do it...and just forgot to tell them about it?

I wasn't angry when I said it, but he did feel badly after realizing what he had been doing. Think reversing the situation made him see how it would make him feel to be on the receiving end of this. So far, no more being left hanging on things.
