I have a parent that has given me a hard time this year. She has a child in my class and a sibling in an older grade. She's a difficult parent, well known around the school, and my principal has had to deal with her on multiple occasions for becoming violent/aggressive with staff and other parents. Anyways....she asked me a few weeks ago if we were going to do a preschool graduation. I explained that we would be having a family literacy night that would serve as our end of year celebration, but that the only grade that does a graduation is 5th grade. She emailed a big long response to how ridiculous that was and that each grade works hard and deserves a graduation.... She hasn't mentioned it again until today. We have 5 days left in the year and she emails me and asked me to buy a cap and gown so that all the children can have their pictures taken in it. I won't even go into my thoughts about a parent asking me to buy something, but I don't even know what to say to her at this point.... thoughts? Should I even respond?
