I don't think you have to be thick skinned. That sort of implies tough and hard.
All I think is needed is an understanding that you cannot control other people.
In with those other not so nice people are others who are not like that and sometimes, most of us post something that someone will read the wrong way regardless.
It's a forum, it ain't life and death and torture at the gates of dawn for not complying.
Apart from Dave Morris @ St Ives. He is the angel of death in disguise. Never, never go down to Cornwall and speak the 'WFP' words in public. He will appear out of the shadows in the mist at dusk and then you will be his to be commanded into a never ending existence of cleaning the same window over and over again for eternity using water with a tds of 40 without payment and without ever being able to dump the customer and get 2 more but you will continuously dream of being able to do that untill time itself ceases to exist.
It's the ultimate torture for a window cleaner.
