What do you think makes a good friend? Season 1: High school

I really love this topic, which reminds me of the sweet time I had with my best friends.
I have a very good classmate who is also sitting beside me for the whole year of Senior 3 when everyone in our class is working hard for college and having no time for fun. Before we joined the new group, we actually know nothing about each other. Long time later, she told me that she thought I to be so proud a person that even did not want to talk to anyone else, which actually she denied after we were chatting about gossips while eating nuts.
We sneaked off the classes we don’t want to attend and do something else, sometimes writing an article judging the current affairs, sometimes asking our lovely physics teacher about some space & time questions. We went to the playground to have some exercises like jogging. When other students were worrying about their homework, their problems of a certain course after the self-study part, we always sang a son loudly through the building, succeeding in attracting many attentions. We never tried to hide our feelings. I thought hard to come with an idea to bring her boyfriend, though they broke up later. She heard my story carefully and comforted me whenever I needed.
Now, when I have some news, no matter good or bad, I am used to call her or write to her for I think some good friends are those who can laugh and cry with me.
