I find myself talking at cross-purposes with my family all the time. Last week, I asked my son by text if he was watching a particular crime programme, and asked DiL if they would be home at 6 pm so I could call by to see them as I knew she was taking the children to their dancing class after schoool. He replied on her phone saying that they were recording it, so later I asked if I could see the video of the children dancing. They both gently implied that I was losing the plot as they were recording the programme not the children, until I unravelled what had been going on. Isn't it interesting that they think it's you that's getting mixed up?
