One of my previous customers was a mentally ill and delusional elderly lady. She called me about a non-existent plumbing problem in her house, supposedly caused by her neighbor, who she claimed breaks in and messes with her stuff. According to her, everything wrong inside or outside her house was because of her neighbor's sabotage. She even mentioned plans to kill him. Not exactly the kind of person you want to turn your back on, but also someone who would have been extremely easy to take advantage of. I basically talked her out of redoing the entire plumbing in her bathroom, and we finally settled on me re-aligning her kitchen cabinet doors that - yes, you guessed it - her neighbor had 'messed with.'
It was quite sad, really. She asked me twice whether I thought her stories sounded crazy, so she was clearly somewhat aware of her condition. I just didn’t know how to deal with someone like that. I refuse to lie, but I also don’t want to tell her she’s losing it. I don’t mind senile people, but I didn’t feel safe around her.
