Enjoy the show. In the last two years, I was at 2 shows where a male companion and me were the oldest. And one show we were only beaten by boring parents which waited in the bar area instead of listening to a great show (imagine grumpy older Gen X being on their phones the entire time). It felt weird at first. Teens and young adults all around me. Every teen had so much swag and I needed Vexillology lesson because there were so many queer flags and didn’t know existed. The shows were nice (Tessa Violet and Cavetown) and I had a great time. Everything was calm, the bar always free, I guess because money is a lot tighter when you are young. If people notice you they’ll think you are a cool dude cause you enjoy good music.
