Hey Boyst,
You make some good points and I agree that what's considered classy is changing. But I do think there are some things that are timeless (but less common these days):
Restraint
Humility
Congratulating someone for doing well
Self awareness
Sincerity
It's been awhile since we met, I think it was at the 2015 TBDHOT. Funny, I don't recall you being drunk, I'd call it "hospitable". As I recall you were discussing the pros and cons of Tinder with my kids. Even got my wife to try some of your 'shine.
