My eldest is home for the holiday weekend, and we were having a quick lunch at a local hangout. Three people came in after us and took the booth behind ours. Immediately, my daughter said "I think that's my eighth grade Algebra teacher!" Then she came up with her name.
Mind you, this child is now finishing up her master's degree at the University of South Carolina. She took two years off between her B.A. and starting her MLIS. She had this teacher a few years back, about eleven. So she got up, asked if this woman was her math teacher,(she was), and proceeded to tell her she was the only teacher to ever make math comprehensible to her.
I could tell the teacher was pleased, and she thanked my daughter for saying so. I hope she knows what an impact she's had on the lives of her students. At least she does for one.
Although my daughter still hates math.
