Truth, I appreciate you asking questions without the fear of what others think. Many people have what I call the "yeah/uh-huh disease". When conversing or listening to instruction, they will look you in the eye and say yeah....uh-huh, even if they're clueless about what's being said. I remember doing this some when I was in school. I think it's important for us to ask questions, even at the risk of people considering the question dumb. Like, you, I have trouble comprehending what I read and sometimes I just need to see the same material in a different format for it to "stick". I truly appreciate the people here that reply and help us along.
