I am thinking of saying something like "oh how kind of you, Mr. Principal, but I do not think that will be necessary at this time. I do believe I memorialized the "common understanding" quite clearly in my email, it really isn't that complicated. Quite simply, the scribing accommodations are necessary to minimize the impact of the disability of congenital hypotonia and joint hypermobility and allow DS to access his education. But how lovely of you to offer since I know how busy everyone is[..blah, blah, blah...] I do look forward to hearing about your meeting with Mrs. Paraprofessional, however. Please let me know how it went. Ds reported to me that she has been much more supportive this week so it seems that your talk with her was productive?"
