Our current neighbors are pretty chill (except for a couple of the 7-8 year old boys who like to try to "pick on" DS or steal DS's things). When we moved in in August, most came over to introduce themselves, one brought over a nice candle, and our next door guy gave DH a plate of shrimp boil!
Before this, we were in an apartment. This little old lady moved in across the hall, and we saw her struggling to bring in furniture and boxes, so...... naturally we went to help. DD, DH and I toted in a carful of stuff for her, told her to let us know if she needed more help, and went on our way.
And a few hours later, saw her toting in heavy boxes again, so again we went to help. This went on for a few days. We even fed her dinner during this time, since all her stuff was packed (she ate breakfast and lunch at some senior center or church or something), and let her nap on our couch, and let her use our air mattress until she could her bed in and set up.
Now, we didn't mind helping her at all, so when she asked if DH could drive a rental truck with some furniture, we said no problem. This woman had plenty of money, so she said--she was single with no relatives and parents had recently passed away--she drove a Mercedes, and was selling her parents home--and she would tell people that she was just putting that money in an account to leave to her church when she died.
The problem came when she picked up 2 guys OFF THE STREET to move the furniture with DH, then left the 3 of them ALONE in a truck full of antiques and DH with no cell phone. I was so worried--they were gone for 5 hours, and I had no idea where DH was. (I didn't know about the 2 guys, until she came home 2 hours into this mess, and I asked where DH was.)
I put my foot down and said no more. She moved onto the neighbors behind us, and told them how awful I was. The same kind of things started happening to them (interrupting meals, etc) and they pushed her off onto the people across from them!
