How?

How can I be so aloof to other people and yet be very friendly with you?
And how can you be distant to other people and yet so close to me?
How can I tell you things I couldn't even tell my friends?
And how can you share your secrets with me even though I don't deserve to know them?
How can I see in you something which nobody else can see when they look at you?
And how can you understand me more than I understand myself?
How can I be me when you're around when I don't even know who I really am?
And how can I say that you are you when you're with me when I don't even know who you are?
