I'd like to give you a mantra that I try my best to live by. "Judge others by their intentions and yourself by your actions". That is to say that other people can and will interpret your actions in ways other than how you intended.
I do actually live by that myself, but there's also people who just can't give anyone a break ever and want others to defer, defer, defer to their whining and complaining. I allow myself to draw a line too. For every time there is a season. :)
