Envied to a friend

There was a man that there are no such people who would be envy about their enemies but there are a lot of people who are envied to their friends. See, you know nothing about lives of strangers and you don't really care about things they have. It is easy fro people to feel okay about all those merits strangers have but there is no way for one to feel okay about advantages of their friends.
For somehow people are envied to those they care much. For somehow people are not able to feel happy about a success their close people managed to get but they are always envy about this success. It is like they feel they are losers but they don't want to do something in order to change it. So, they prefer make things worse for their friends than make things better for them.
It is the envy that can turn the best friends into the greatest enemies. Such a tricky psychology and mentality of people. They are envied to their friends and they grow mad about success their friends managed to gain. This is the beginning of the end of their friendship. People feel okay when their friends are just the same losers with them.
Though, people will never manage to feel okay with their friends to be more successful. I guess that is why in most case friends are people of the same social status and the same income. Though, it is wrong to be envied to a friend and to sacrifice a friendship for envy.
