Teachers get very nervous when little children write sentences like this one. :) I’m not surprised she changed a word to try and ‘lighten’ the homicidal implications. I’m dying laughing over here. LMAO.
Now, the problem is that she was dishonest about it (or she REALLY had no business teaching children), and instead of telling you why she found it inappropriate for school (if that was the case; i’m guessing) so that you could avoid a similar incident going forth, she covered it up as an error on your part, which you were smart enough to know was wrong, leading you to assume the mistake was hers. I’ll bet you never looked at her the same way again, did you? even as a little kid…
And you don’t sound like “that kind of parent” at. all.
People don’t so much mind if parents brag on their kid’s strengths as they mind when parents are constantly bitching about how other people are underestimating those strengths. saying, “My son is WICKED good at maths” is different from saying, “My son’s algebra teacher is an idiot. She’s harder on him than she is on the other kids, because she can’t stand that he’s the smartest kid in grade 8.”
See the difference? you’re good. :)
