I agree, but it would be good to be polite. For whatever reason, she really wasn't that day. And at this event, there really wasn't a line per se....at all. At another location, my dd really wanted to meet Kyla Ross. I am not into this wait in line thing, but she had some real reasons that were very valid to her for meeting her, so we waited.....over two hours....I read a great book during that time and she did homework....and Kyla was just lovely. And we were literally 5th from the last in line.
Yes I know they are probably over it more often than not, but it's like models on the runway....it's a job, and you need to perform. And they can definitely choose not to do these signings, there are many out there who don't do them. I would never want to be famous and have to sign autographs because I honestly wouldn't be able to pull it off in terms of doing a public signing with people waiting in line to see me. I would start saying silly things and get myself into trouble. Obviously I am not famous, lol. But if I were, I would opt out of those kind of situations.
