I'm the opposite; I'm seeing more and more shows. It's relaxing to me, and it's fun. I also don't mind going by myself, so there's that.
Just this Saturday, my wife got a thing on Facebook that some dude she went to high school with was playing a local bar in his Deep Purple cover band. Turns out, the guitar player is REALLY good - Jimi Bell; something of a local hero; he played with House Of Lords and now is in Autograph - so I went. I was by myself (though I know the owner of the place) and went and sat at the bar and watched the band. Got talking with the dude next to me and a couple that were there and had a great time. A friend of mine from law school and I go to a lot of shows together (Cram has met him a couple times) but if he's not into it, I'm not necessarily staying home.
Being "alone" has advantages; I can hang if I want. I met Gary Barden that way, and got on stage with Gene Simmons that way. It blows to not have someone to share the memory with, but so be it.
I'm also noticing that shows aren't nearly as loud as they used to be. I don't know if it's regulation, or something else, but while Jimi had a full Marshall stack, the sound was pretty reasonable for a small club (I think the place fits 125 or so for a show like that).
