How do you know who your friends are?

The answer to this question depends on when this question is asked and how well the person being asked knows his friends.
For example, if you were to ask a 4-year old child this question, a possible response would be, "Those who play with me are my friends". But if you were to ask an adult this question, his or her reply might even be to ask you which friend you are referring to.
Thus it is only good that we treat all our friends equally at first, and not go with who we feel, and completely sure, is a good person. Instead we should observe their behaviour, their mannerism. Only after we have done that can we be more sure of who our friends are.
Many people, due to crimes of theft, end up in trouble. But what is the cause of all this trouble? It is, in some cases, due to the fact that they did not assess their friends and ended up in bad company. Following that they are coerced to join them in various offences and when they finally get into trouble, the ones who run first are he ones they called friends in the beginning. After that you see them in jail regretting their actions and their choice of friends.
To conclude, isn't it better to first judge your friends and know who your real friends are, rather than get into trouble later. After all, friends are the most important people after family.
