Seeing the Heartless Bastards tonight with a good friend from high school I reconnected with when he moved back to LA a few years ago after spending a couple of decades living overseas.
He was one of the friends I'd regularly see concerts with as a teenager, and now in our mid-to-late 40's we're regularly seeing shows together again.
(Unlike me, he's managed to hold onto a few of his 30-year-old concert T-shirts.) He was able to grow a full beard by sophomore year of high school, so back then he used to buy all of our beer. It's now a bit easier for me to return the favor.
