Ahh yes. Isn't it wonderful when parents take an active role in their children's education? Teachers aren't perfect, they make mistakes, too. I suppose that was the reason why one of the moms took it upon herself to correct the teacher's lesson. The topic was what plants needed to live. As it turned out, the mom happened to be a grade school science teacher, so ofcourse she knew what she was talking about. The teacher had helped the students draw on their notebook water, air (symbolized by wavy lines) and the sun. The next day, the teacher was surprised by a huge red X drawn on the sun and a note by the mom correcting her, saying that plants don't need the sun. Oh my God. She's a grade school science teacher?!!!
