My best friend of 39 years let slip last year that his wife talked him into going to operas with her. Mind you, this is a guy who I've gone to many concerts with over the years...rock concerts. Seeger, The Firm, Deep Purple, Rush, Springsteen, etc. Too many to recall and name them all at the moment.
Opera. I said like what, "Tommy". He said no, real live opera, complete with an orchestra, people dressed up all fancy, etc.
I was so hurt and confused. I punched him. Didn't know what else to do. I still don't get it.
