Not sure why you deserve more pity - being surrounded by screaming 12-year-olds, or being subjected to Taylor Swift's live singing.
It was actually a pretty damn good concert. I had a great time, she puts on an amazing performance that caters to her targeted audience. I have been to many concerts where concert goers have sung along but it was nothing like what I saw this evening. I told my wife when our children want to go to concerts like this, she's gonna have to be the one to go.
