>>>.The Lubavitcher Rebee ZT”L used to say good morning to anyone he met in the street, even women. (I heard this from someone who constantly saw this.)<<<<
I think he had the right idea.
Every human society has greeting rituals, for some reason they are very important to us psychologically. If you think they are not, try not greeting everyone for one day, and see how many people end up disliking you.
I wish you all a wonderful Tuesday.
I have worked with people who always had a big smile and a heartfelt greeting for everyone, and they made me feel good. I wish I could always do the same.
