He probably wasn't thrilled when she did and will call her out if she does it again, which I doubt she'll do.
I guess it just depends the people....I am the type that wouldn't say anything if a hot guy did it but wouldn't like it if someone I found completely unattractive did it. I know it may seem shallow, but atleast I can be honest about it. Not sure why exactly Kelly didn't like it, though in the middle of an interview isn't exactly good timing either. I admit I feel bad for Clay, I'm sure he wanted to leave right then and there.
I think the Kelly and Clay saga is unfortunate. They were both wrong and Rosie is the person who over reacted more than anyone else. It'll be forgotten in no time, I hope. There are worse things happening in the world.
