There a real easy answer to that question. The reason they should say “hi” is because they want to. If they don’t want to, then by golly, they don’t have to. It’s as simple as that. Personally, I am not going to foist upon every rando on my block or in my apartment building, the burden of meaningless formalities just because I go to bed every night closer to them than 8 billion other folks’. I let them be so that they can get about with their busy day. That’s just plain considerate.
