I went to a local band performance where the median age of the audience was around 14, with me as a 40 year old in attendance. I felt self conscious for about 2 minutes until the show started. Then I didn’t care anymore.

Banger show. I’m glad I went.

You do you, dude. Don’t worry about what others might think about your attendance. Vote with your dollar. Spend it on stuff you want to enjoy.
