'As I mentioned...'
'As I said earlier...'
'I did mention this....'
Ok, he is correct. He did mention it. Once. In amongst other things in a long, detailed email. I am a trainee and trying to remember a lot of things and SOMETIMES I need items of information to be repeated. Not everything, just some things. Using phrases like this makes me feel embarrassed and resentful and frankly does not help my productivity as here I am. I make a particular effort not to use phrases like that myself as I am very conscious about making people feel small.
Argh. I HATE IT.
