I have a family member who pokes the person she's speaking to in order to emphasise a point. I have told her not to do it to me (and try to maintain distance when she's talking now) but she got all affronted and still hasn't stopped.
To explain, it's like a tactile exclamation mark in her case, that's the only way I can understand it.
Is this normal? Do other people use prods while conversing? I'm baffled.
What other weird behaviour do people display?
