Bugger off

There is a thin line between what is swearing and what is a polite request :) Eg: Bugger off is more like a fantasizing request than a swear word depending on the person it is used on, the tone and context. I guess some people have a line that is thicker than others. But now this begs the question why swear at all. I like hanging around this person who doesn't believe in swearing. Of course i find that i swear a lot when i am excited and amazed. But why should i? Its gonna be something difficult to unlearn. But i'll be all the better a person if i can.
