People cannot live alone, they must have a family, friends and live in a society. Wemeet thousands of people in our daily life but we can like a few of them. The relation between us and them starts when we find some mutual similarities in our lives. However, it is only a little of the process. We search for some characteristics which are important for us. They can be dependability, decency, sympathy, helpfulness and craziness. I think dependability is the most important character in a friend relationship. If you rely on you friend and your friend also trust you, other problems can be solved anyway but you do not rely on your friend, even when you are undecided about your friend’s reliance, you can loss everything. Another important characteristic is decency. We have a lot of obstacle in our relationship with friends. We can overcome them with these two important characteristics, dependability and decency. Other characteristics are sympathy, geniality, helpfulness and a little craziness.
