Happy or Not?

How can we decide whether need to be happy or not?

Happy for what yourself have achieved.
Unhappy for what your friends have failed to achieve.

We usually couldn't explain how happy we were after getting something which we didn't expect to get.
Felt like the world are very beautiful and wanted to share the happiness with friends.
But then realised some friends were sad because they failed to achieve what they wanted and needed to achieve.

Achieve vs not achieve.
Happy vs not happy.

A situation where I thought that everyone have done a great job! Miss number 1 told me that she got a 70 marks. Wow!!! Happy, I m happy for myself and her. I felt like wanted to jump around at the corridor. I asked Miss number 2 for her marks with joy and........... she failed.
How should I react?

I also don't know.
At that moment, I just stopped and said,"Sorry because I suddenly don't know to react. "
Sorry if I accidentally hurted anyone, I really didn't know and really sorry.

Hope they will be fine soon.
Fighting for the next times.

Although we couldn't hoping around for our results together, but I knew that we have done our best.

Anyway, claps for myself. ≧﹏≦
