If our goal is to be honorable mentschen, implementation entails only some easy steps such as: a used tissue should not be left on a desk or the floor with the expectation that someone else will dispose of it.
Don’t cut a line – even if you think your time is more important than others (this applies even to the access ramp to the Brooklyn Bridge). Offer your seat on public transportation to one who is older or weaker (I once offered a seat on a bus to a woman that I thought was pregnant. When she told me that she wasn’t, I was so embarrassed I said that I was getting off anyway – and had to pay double carfare).
Treat people with whom you disagree with respect and fairness. One is entitled to argue – even with one’s spouse – as long as you are fair. Fair means you stay precisely on the subject and don’t dredge up, “And you always/never do this…” Two words to avoid when disagreeing with someone are “always” and “never.” Abaye argued with Rava and Beis Hillel argued with Beis Shamai, but their arguments were always on a specific point, and accordingly respectful.
I’m just getting started, but the column length has lapsed. This is not rocket science. A little consideration and we’re on the way to being honorable mentschen.
