My sister had to answer a test which will decide her future university.

As it was my time, I could join the University of Medicine. But I couldn't teach her well.

She doesn't get the marks she wants. 

I am disappointed with myself. I am feeling like I am not a good sister to her. I could get the best university in my country but I can't help her.

Now she is crying and I have to watch her with a breaking heart.

So sad…………………
