It's really starting to wind me up. I keep seeing threads where a PP refers quite clearly to a person as 'he' or 'she', or 'my mother', 'my daughter', 'my son' etc - but then people responding switch to 'they'.
I've just seen one. A poster whose neighbour is moving her post. She refers to him as 'he'. A few replies in and he's suddenly a 'they'.
