100% sure....yes. it's odd and weird that some would take that as being arrogant or that I feel superior in some way to others, but nothing could be further from the truth. They make it out to be a bad thing, because I'm sure, but I'm not sure why, except for those reasons I gave. There's nothing wrong at all with being 100% sure. I know what I have experienced and that's why I know for sure. Others can do the same exact thing if they wish to. Some think there's no such thing as being sure, but there is.
