It all drives me bananas!
I hate seeing the schedulers and the guidelines with grammatical errors; it makes my hair stand on end like fingernails on a chalkboard!
My husband tells me that I should edit for various people and places. In the past, I would receive weekly letters from teachers that my kids had, and there would be errors every time. And the monthly letters from the school itself were horrendous. Why wouldn't companies, institutions of education, and people who want to appear smart *NOT* proofread, at the very least? Or possibly hire an editor?
And "legal notices" that come in the mail from my small hometown are just awful! They are so poorly written that it is difficult to follow what it is that they are *actually* trying to say!
