My mum and MIL and SIL all do this. They live in different places so it's not regional but is it A Thing?
Basically I will be talking to one of them and they will try to guess what I'm going to say and say it along with me. So they say the same words as me just a nanosecond behind, finishing off half my sentences with me.
I hate it! It makes me feel really stressed. And it's so weird.
Do other people do this? If you do can you tell me why?
And how can I stop it without being rude? Last time I asked my mum to stop it she was really hurt and said she didn't know she was doing it.
