Nasty Words

I was at the pool today, Bob, a friend and I were talking about nasty words. We all have a vulgar vocabulary that paints a self defeating picture. I'm not talking swear words. I'm taking some of the first words we teach our babies. I'm just going to list them and explain as I go:
1. "Ya, but" (this is a very rude way to disagree with people)
2. "I can't" (YOU CAN DO ANYTHING!!!!)
3. "Problem" (there are only "challenges", the only problem is death if your a bad person)
4. "umm, ahh" (seal talk is something I really need to work on)
5. "Mine" (were not taking anything with us, plus it feels great to share) and last but, not least...
6. "NO" (why are we so afraid not being liked by people? I think it all stems from fear of this word)
