I know someone who is setting themselves up as a counsellor. For many reasons I think they will be crap at this. They aren't qualified for a strat. Have a qualification which is about equivalent to a GCSE in counselling. But, because of serious issues in their own past, they are also completely and utterly unable to deal with people being angry. I don't mean violently angry or out of control, I mean, a bit pissed off or snappy or irritable.
