I had an OCD neighbor call CPS on us 2 years ago almost to the week, reporting that we had feces around the house and that I left my kids home alone unattended. HOW they would know this- is beyond me. I was 5 mos pregnant with my 6th and it was spring vacation/spring cleaning week- so they CHOSE that specifically to surprise us when all the kids would be home and make a visit. NO LETTER, no call. I had 2 CPS workers AND an officer, no warrant- just a report.
What does your neighbor having OCD have to do with anything?
