Do You Have Good Friends or Bad Friends ?

I have seen so many people's lives have been destroyed because of the friends they have. Friendship is good, it gives us the sense of fulfilment but nowadays we find so many friends from the social network and somehow we thought them as a real friend. Someone may have 3000 + followers on facebook and he/she has so much proud on this but at the time of any obstacles only real friends like wife, husband, kids and close ones come to support not those 3000 followers, they might just comment "Don't worry everything will be alright " "Please take care" or so.
It is really cruel to neglect our closer ones and it also shows how much ungrateful spirit we have.
I know one couple who did a love marriage, they have kids as well, but from quite some time wife got so many friends on facebook then they started meeting up then partying starts, then behaviour patterns changes because she tried to copy the lifestyles of her friends and then finally what happens "Disharmony in the entire family". Husband felt frustrated emotionally and physically both, whenever he came home she was always on phone with her friends, he some times has to grit his teeth to cover his anger. They are still living together but I don't what is happening with their kids on psychological front, they must be feeling sad about their father and mother.
Devil always enter very sweetly, and destroy us. Are they real friends who are not understanding the needs of eachother's family, are they real friends who constantly nagging their spouces. Are they helping in the growth of eachother's families.
On this front I just say, we always do friendship who supports us in our thoughts, who is on the same vibration as we have. But that is the real problem, if we surrounds ourself with this kind of friendship them we certainly could not be able to grow in life, life will always be full of problems because they always talk about the problems not the solutions. They don't guide us correctly because they only speak those words which we want to hear, they only do the behaviour which we like. But is it correct ? Aeroplane is able to fly because of opposite winds, similarly, life will be able to expand and grow when we have correct friends and who is the correct friend.
In Buddhism, I have read the beautiful lines which say," If you befriend sombody and don't have the mercy to correct him then you are not his friend, infact,you are his enamy". Which is absolutely correct. Another lines from Buddist text says ," If you have the choice to die from the mad elephant or bad / cunning friend then whom do you choose". It is better to die by mad elephant because he will only inflict pain in our body not in our mind but the bad friend will inflict pain mentally and physically both. Another lines which I cherish on this subject says you can judge everything about the person just by meeting his friends.

So the choice is ours, which friendship we wish to choose, whether we wish to grow in life or wheather we wish to put our life on downward trend.
