Like all shows where standing is involved, this was my view.
I overheard a girl behind me say, "I'm not nearly as short as I feel at a concert." Truer words, sister.
Not only did we leave early but we also went to dinner instead of catching the opener. Because there is nothing worse than an opener. Especially when you're in a venue with no seats. By the time the main act gets on stage you've been standing for 2 hours with a few more to go. It would be fine if you were walking laps or something. But you're just standing while the blood pools up in your ankles. And I have found that the time between the opener and main act is comparable to the time between the dinosaurs walking the earth and humans showing up. Which is approximately 64 million years. I looked it up. The only thing better than skipping the opener is going specifically for the opener and then leaving before the main act comes out.
Isn't it grand to be old enough to leave a concert early? When I was in my 20s I would never have done such a thing, even if I was tired or having a miserable time. Your 20s are a time for late night fun, even when you're desperate for your bed. And I was, often. I think more than anything age gives you confidence to say, "I want that, not that," and not be ashamed of it. You can follow it up with, "So what if I'm old. I'm going to get like 5 more hours of sleep than you, sucker." Because being older also means you can speak your mind and people just laugh it off.
