Someone asked a question about how frequently young people have time to socialize and it made me think about what people do with their evenings. I recently asked my son to go to a concert (free ticket to see a band i know he likes) and he declined because it was an hour away on a weeknight. If we invite our kids or niece/nephew to dinner they always want to go at 6/630 which feels so early. Edit: Kids are 30ish.
I wish I had that rule back when I had roommates, one of which would constantly beg their wife to get delivery. It always caused arguments and would hold things up too much.
