Well, I know that you can tell that

I have a problem.

It seems that people want to use the curse words in thinking because after all they are just words, just have to be used in the right situations.

Something happened when I thought "not a nigger."  It was a big deal.  I couldn't at the time stop it from coming.  So, later, the reason I thought it came up, it just hurt me a lot.  Some things happen.  It's like when I think someone is gay to me, though.  :p  At the store, I thought of the word, and the cashier just smiled, a teen or young adult boy, and we exchanged looks that we were Celtic.  It was funny and made sense at the time, actually...
