Oh, this annoys me too and it's SO common. People don't read. When they do, they don't comprehend what they read. I'm generalizing, of course, but sometimes you really need someone to just please read.:grrr:
If e-mail is the only way to communicate, then you shouldn't feel bad at all about asking as many questions as you need to. You're doing exactly what you should be doing. :thumb:
May I suggest that you use a bullet point on each question, a large font and the simplest, clearest language you can. Personally, I'd write any e-mails to her at the elementary school level. Not to be insulting to her - just to make it easier for her to read and respond if she's reading when she's tired/ill/upset, etc.
Good luck and keep venting as needed.
