Friends are like your flesh; when they suffer, you feel pain

We spoke of a guy who many people hated before. He was a Gemini, who loves to gossip and be a subject to gossips. The former never happened, however the latter is now part of his life He lives in solitude, where he is socially rejected. He has to hide among shadows to protect his 'face'. As a matter of facts, he had already lost his in an unforgettable incident since the year 2006, where he encountered his friend-turned-nemesis.

My friend told me that I was indeed similar to this guy. Similarity is not indifferent from congruency. I am contrast from him, given that I am sensitive to changes in life and is willing to seek for higher purposes in life. Why he's different is that he is very flat and predictable; a leopard can never change its spots. He is always depressed. He fakes laughter all the time, even though he should have known the facts that WE ALREADY KNOW THE TRUTH, and that we care for him. When he gets hurt, we feel irresponsibility in us. Ironically, the same friend who said that we are similar has already 'adapted' to his depressions and couldn't care less for him any longer...

Any suggestions to help him?
