earlier you staed 'patronising'
if it had been me, i would have gone for....
"hang on mate, that seemed a little patronising, whats going on?"
conveying your point via a question is in my opinion much better than a line in the sand with a statement.
its subtleties like this that are the core of tact in communication - all it takes is a re-read and asking ones self if it had not been written by you, how would you interprit it.
i dont want to start a 'thing' - but please ghost - this isnt the first time, just a touch more consideration from you and everyone else and we could all turn the escalating hostility and potential bad feeling right down.
