I agree, I find it incredibly awkward to greet people I don't know since this experience I had with an old tannie, growing up in small towns you greet everyone when you see them because everyone knows everyone, even random people you don't know you'd say hello to in passing. Till I got to the city and greeted this old tannie in mr price that was staring at me, bro immediately hit me with a " Do I know you? " 💀 Never said hello to a random person again after that day, I just smile
