It was a sunny day. I had finished my homework and called my friend, Anna, to go for a walk. Anna gladly agreed to go outside, because she has been cleaning her room for hours already and needed a break. As we had planned, we met at the park near my house. Anna and I started walking and discussing some problems, but suddenly she fell! I had helped her get up, but I noticed that she tripped over a beautiful old-looking vase. After a minute of examining  the vase we had come to the conclusion that we had to bring the vase to a historian. We had been searching for a historian in our city for quite a long time but couldn't find one. That's when we decided to bring this vase to a museum and have it checked. After we gave the vase to the professionals at the museum, they explained to us that their expedition had been looking for similar vases for years and this is the one they've been searching for for a month already. We were glad to contribute to the museum's work. Now the vase is where it belongs-in a museum

Social dependence requires not only the struggle against it but also its awareness.
