Dusty, you are right. Both ways are correct. I still think it is weird that you can spell it both ways for the same meaning. Are there any other words that mean the same and can be spelt 2 different ways?
GBRoxon, that was very interesting what you said. I kind of like your explanation. That's what is so great about forums - getting many different views from people all over the country from all walks of life. Thanks everyone for your replies.
