The answer

I live en the shadows
I have to be careful
Nobody may know who I am
Mustn't let anyone in
I have to cover the clues
Consider which words I'm using
Can't let anyone see through the disguise
I must live alone, so nobody will find
Find the truth
The answer to why
Why be different, when you can be like everyone else?
Why talk with people, when you can be silent?
Why have friends, when you can live your life alone?
Why love people, when you can forget your emotions?
Why forget the pain, when you can make it stronger?
Why see the light, when you can live in the dark?
