I chose this topic because friendship it is good feels and now it’s important to have a good friends. Friends can support you in difficult situations and they don’t betray you. Friends can be different, for example: animals, people, books etc, but there are have different assumptions about the concept of friendship. First – If people can’t talk on different theme this is means that they can’t be friends. Second – Friends – it is one soul that live in two bodies.
If people can’t talk on different theme this is mean that they can’t be friends. If people can’t talk on different theme it is not mean that they can’t be friend because: 1. Friendship stay on action. We can say all but we can’t to help for everybody. Friend in need is a friend indeed. 2. Friends can be different some friends we can sit without a word but feel very good and they can the best friends.
Friends – it is one soul that live in two bodies. I think that it true because two persons help each other in difficult time. If people don’t support we all have be stress. If people associated a long time they become the same in outwardly. They can easily understand they have the same think. This persons have the equal interests. For example: they like to play tennis every Saturday. Friend do that they like. Friendship – on the whole stay in understanding because when people don’t understand each other they swear and can’t agree with different person. Really friends –trust, respect each other. They can say secret and how that they help understand and save this secret. If we don’t respect our friends, people, we can’t associated with different people and we would be alone. Loneliness is very bad feel, because of it we could go mad. That why, we need in associated with people. And have friend that can help, support, listen to the whole and have a one soul in two bodies.
