I am glad you are all so understanding! Without facial expressions to convey the meaning behind written words, so many people take things completely wrong and decide to get their feeling hurt, or worse, start a verbal war of words and then both sides get upset. Not worth it.
If I personally took offense every time Zuzu corrected my grammar and spelling, I'd be a basket case.
Instead, I welcome it, learn from it and beg her to be my teacher/spellchecker before I turn in my work (aka long thread posts)
Of course, it's my poor memory (or too fast typing) that I can then blame when I repeat the same mistakes over and over.
