When I was a kid my parents made me go to operas and concerts figuring this would make me a good intellectual from their generation.
I imagined other concert-goers staying up till all hours talking afterwards, instead of going to bed so they could be in the shittiest public schools the next day.
Anyway, one of the awesomer bits of adulthood is listening to opera in just my boxers. Verdi wrote some completely gorgeous stuff and it's ridiculously awesome when you can walk away at any time.
