I don’t, but DD1’s care staff have to! It’s in her care plan! She tends to take them talking with a straight face, as them shouting at her! I don’t shout at her very often; but I guess on the odd occasion I do, she can tell!
(There was the time, I’d bought some shortbread back from Scotland for my mother and brother. DD1 sneaked upstairs a couple of times, and wolfed down both boxes! I was angry with her, because she knew then, stealing was wrong!
There was also the time, DD2’s best friend’s mother bought me a box of chocolates back from Hongkong for getting a locksmith to break into the house, to save the rabbits’ lives. Best friend gave us the wrong key to the house, to look after the rabbits. I was only talking to DD1’s SW for 5 minutes, and DD1 wolfed down the whole box of chocolates in the kitchen!)
However, if we tell her a joke, we have to have a big smile, otherwise she could burst into tears!
