I watched Dave Letterman this evening, and his guest was Bill O'Reilly. Their discussion gave me food for thought. I used to watch Letterman every night when I was in high school and through my first couple years of college. Nowadays I watch The Factor with Bill O'Reilly.
I think the difference is that I've grown up and I've started thinking for myself. Letterman used to be good enough for me. I just wanted to be entertained. Now I like my entertainment to have some substance to it.
