As I have got older, I take a much more laid back approach to it all.
If you dont know, you dont know.
What might be obvious to most, can be like rocket science to others.
Might be some that think they do know it all, when in fact they know very little, but I must admit it annoys me a tad, when someone is made to feel stupid for asking a question and all they want is the answer.
Someone just moaned about someone asking a simple question on F/B, that all you have to do is "google", it and you can find the answer. But then thats what's the F/B groups are for, finding out.
Takes all sorts I suppose, ignore the rubbish and try and help the genuine queries.
Just a quick heads up, make sure you know the date when your MOT runs out. Cough !!
