i had to take a test in order to graduate college but i really did n't understand the subject at all and could n't get anywhere studying on my own . after a lot of agony my sister sat down with me and went over it in detail . she really helped me to learn and understand it . thanks to her i got a great score on the test ! that is very nice of your sister ! i thought so . i really am so happy with her . do you think i should do something nice for her in return ? yeah , maybe you should get her a gift of some sort .
My sister helped me understand a difficult subject, enabling me to pass an important test.
