Maybe they don't speak English; assuming you didn't greet them in Klingon or something like that.

Meh, 1st one's free. Give them the benefit of the doubt. After that, assuming it's a pattern, they're shitbirds.

some people! the house across from ours was sold recently, and when i saw someone coming home, getting out of her car and going up the steps to her new home, i called out a hello and introduced myself. she turned and talked to me for a short while, introducing herself too. then i didn't see her for a while, until today, when i greeted her again, and again she was friendly and we chatted a bit. i don't get out much; i might not see her for a while, and to tell you the truth, my eyes are bad; the first time she said some other young women live there too and they all work in the same place. so for all i know she might be a different neighbor from the one to whom i initially introduced myself! but it is nice to know someone friendly is living across the street, and not someone like your neighbors, who really should have said SOMETHING. they might have been in the middle of a fight and not been in the mood to talk but they could have waved, or tried to smile, or SOMETHING.

How rude! That would have ruined my whole day, but I hope it didn't yours.

That's kind of ugly. A wave is not a commitment. A smile is not a promise. It costs nothing. I don't understand that. Someday they may need a cup of sugar.
