If you are requiring people’s help. If you are relying on other people’s good will and their desire to help you. Be nice to them. If you can’t be nice, be civil. DO NOT call them children. DO NOT call them retards. DO NOT accuse them of incompetence in any way whatsoever because if you do, they will stop wanting to help you. They’ll still do it, but they won’t go out of their way anymore, and believe me when I say that a lot of time your stupid and insignificant problem WILL require them to bend the rules for you . . . and if you piss them off then they have no reason to do so anymore . . .
Just a warning.
