I had to take a test in order to graduate college but I really didn't understand the subject at all and couldn'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.
