Avril was sick when that meet and greet happened and she didn't knew what disease she had back then.
She didn't knew if she was contagious.
That's the reason for the distance between her and her fans in THIS ONE meet and greet!!!!
She did so many meet and greets over the years, with hugging, kissing, and everything else.
She was sick.. people are so mean dissing Avril all the time.
I'm so proud that she defends Katy, Britney and Kanye too!
