My first lesson.

Yesterday I left one important thing at the room. Then  somebody closed this room. I didn't know what  to do. Nobody had the key. But I tried to find the key which fits the door. I was searching it for a long time. And then I found it. 

This story teached me: it's possible to open any door. But sometimes we are too lazy to open the closed door. And I think it applies not only doors, I think it applies our life.

P.S. Sorry for my horrible English:))
