....why post if you don't know what you are talking about?
You're right, I don't have an answer to your question.
I occasionally post silly answers to questions because I enjoy excercising my sense of humor. It's fun. I notice that others do the same, so I'm not the only one that thinks so. It's just as much fun being on the recieving end of good-natured humor (good-natured being the key), as well, so I can take it as well as dish it out.
I always try to do it in a non-offensove way, but still, not everyone likes it. My apologies. I will not reply to your posts unless I have a serious answer.
