Please don't ignore the advice about attitude and grammar.
If a pilot was flying an aircraft that you have worked on immediately prior to their sortie, they would want to be confident that you have paid attention to detail, weren't lazy and cut corners, have accepted criticism like an adult and corrected your mistake to the best of your abilities and have remained calm with a smile on your face while you were doing it. They wouldn't want to have to rectify your mistake by pulling the handle just to give them a chance of finishing the shift they started.
It might seem like some members are being tossers for the sake of it, they probably are... but try to see it as advice that will hopefully keep your conscience clear, aircrew (and those on the ground) alive and you out of prison.
