I don't keep up with her on Twitter, but... that is part of what I like about her. If she is thinking it, she is saying it. She is who she is. There is no guessing what her opinion/thoughts are.
I have to REALLY like someone to go see them as well...even then, I usually don't go. I am so not fond of crowds.
However, I bought the tickets for hubby's Christmas present. Since he and I both like her...
When she added Pat Benatar, for the opening act... even better!
