She was surprised seeing me asking her about math, because i reckon that i hate math, but i'm trying to do all my best to get good grades. So, how i said, when she saw me, she was so happy, because she's a good person and open all the time for questions about math, even if sometimes she's such a boring person, she's a good soul. She explicated to me what i didn't understand, and everything was fine. I thanked her and i went to my class, where my classmates waited me.
