"Do not assue from your lack of knowledge that everyone lacks the same."
where i come from that's an insult. and you do that 20 times a day to 20 diffrent people
Where you're from is irrelevant; this is the internet. That isn't an insult. "You're lack of knowledge" doesn't mean that the person being addressed is an idiot, just that thry aren't knowledgable in the subject at hand.
