hey don't feel bad! some people are just that way. our next door neighbors.... when they built their house my husband would wave and say 'hello' and they would look down and walk away and totally ignore him. he was like 'what the heck??' they never once spoke to us. and then, last summer, we found a big hole in our fence. evidently it had rusted and the horses or cows had pushed it thru. anyway, it was about 6ft inside the property line, so when we replaced it, we wanted to put it on the line, made more sense. so DH found the survey pins and had the transat (sp?) and we were marking the line all the way down. well this 9mos pregnant woman comes running up to me screaming 'WHAT DO YOU THINK YOU ARE DOING! THIS IS MY PROPERTY.' i was stunned. i said 'uhm, we're trying to mark the line so we know where to put the fence'. she said the old fence was hers, etc, etc, etc that the survey pins were wrong and that we were on her land. i was contemplating chewing her out big time when my DH came up and diffused her a bit. he just said 'oh, i didn't know the survey was wrong, can we see a copy of the one you have?' and she said they'd bring it over, and of course, they never did.
anyway, this is sort of a ramble, but its like they hate us, they ignored us for nearly 2 years, despite our best efforts and they made the choice to have our first interaction be the woman screaming at us.
spotted crow was right on, some people just suck.
i don't expect my neighbor's to be my best friends, but i try to be friendly with them, etc. my rule of thumb is, i want to be friendly enough that if my house was on fire, they'd call the fire dept. and i'd do the same for them.
i know its hard, but don't let 'em get you down. we like you. life can't get much better than having a bunch of chicken lovers liking you.
