Advice for dealing with crazy neighbor

[Liam Goble]

So I have a crazy neighbor.  Crazy as in Bat Guano Crazy.  She hand feeds rabbits.  She and I had a cordial conversation, where we both shared some very personal stories and at the end of the conversation she told me that she keeps a shot gun by the front door and if anyone knocks, it's shoot first, find out who was there second.  

In August, my property was hit by a drunk driver.  It caused the building to be condemned until the structure could be fixed.  The residents in the side that was hit returned to the duplex, but the other family moved out.  The grandmother (in the 'other' family) was friends with the crazy neighbor.  

The crazy neighbor complains about the tenants on the far side of the building.  She claims that the kids are a nuisance and that the parents yell all the time.  In addition (and this was the big one), my residents had not installed curtains in the year that they have lived in my duplex.  

I've been working on the side that the 'other' family vacated and every time I enter or leave the house, the neighbor is outside asking me if I'm going to find other "hooligans" to rent the side I'm working on now (I replied "no, you've got it wrong...not hooligans, hoodlums!"  I'm kidding)

All joking aside, has anyone else had issues like this?  I've gotten to the point that I just ignore this lady, but I feel bad for doing so, but she's making life miserable for me while I'm working there.
