Okay, okay - I admit it! I watch it because I want Chuck and Blair to get together and, eternal optimist that I am, I keep thinking that somehow, some way, forgiveness will be dished out, the past buried deep and against all odds Chair will ride off into the sunset to make with the happily after. It's more aggravating than waiting for Ross and Rachel to get themselves sorted out. If I can make it through ten seasons of Friends for that, I can make through six for Chair. And, while Chuck did try to trade Blair for a hotel, he never slept with another girl while they were together - unlike some people I could name (who, I agree, were not on a break at the time).
