What would you think if the person you were offering a helping hand was saying what if I do it this and you not knowing it is not so good told them again and they then said again what if I do it this way . Also I have changed engines in cars brakes on vans clutches in tractors . Engine rebuilds including fitting an alternator. It is a different sort of skill they only fit one way . If it wrong they won't go back together . You can get a long way into a tile job when you can then realise it is going wrong .you know it is disrespectful to refer to someone as a third party when that person is around,
I wouldn't expect you to come into my job today and be able to do what I do, but I would make allowances if you were trying to learn, when I have a much better level of expertise than someone I offer them a helping hand up rather than look down and mock them.
anyway, I'm very grateful for all the advice, so thanks.
