Oh my word!! This lady sounds nuts! Be thankful you are finally done with her

I am like you and would be royally pissed off too though. I know that I provide quality care so if someone told me to "do my job better", you can bet I would be seeing red!! I have had a few awkward conversations with parents in the past and thankfully was always able to keep my cool. I don't know what I would have done in this case!! I think I likely would have just hung up and texted her to call me when she had a chance to calm down and wanted to talk like a mature adult.

It makes my minor complaints with past and current parents seem almost enjoyable! lol. That is great that you were able to find other clients!
