I was speechless...totally!
She used to come regularly during my work hours for help with that subject and I really dont know how I helped her solve those home work problems. I will somehow make sure I get the answers at the back of the book (using all the theorems that I have ever read about). Everytime she left I was so relieved. It was the same nightmare everytime she came in for help with that subject. Finally the semester was ending and I was the happiest person to know about that (not because my classes were also ending for that semester, but just because I can get rid of her). After the exam, she comes back and tells me she scored an A in that class and had come back to thank me for all the help...I was speechless...totally!
