@ossobuco,
I pushed a bully in highschool to physically harm me when I replied his "**** your mom" with calm reply of "So you are saying it is more intelligent to say "**** your mom," in a loss of words stupidly, rather than to articulate yourself clearly?"
I may have had a bruised eye, but I kept my dignity.
The funny thing is we are now close friends who keep in touch with each other. A little cussing doesn't hurt anyone. Ok maybe a little bit, but it's nothing mendable.
