I got only two pieces of advice:
1. Men should be masculine, and women should be feminine.
2. Always take a handkerchief on a date.
I have found the former advice not particularly useful, since gender roles have changed considerably in the last few decades.
As for the latter, I carry a handkerchief everywhere I go, despite the fact that I haven't been on a "date" since I married my wife 38 years ago.
