Friend?

How do you end up relationship with your friend?
I feel something strange these days, I think somehting is going on. Something is happening very silently...
I am trying not to care, and see what will happen next.

What would you do if your co-worker wants to be a friend with you?
I see a work place just as a place to work, not a place to make close friends because I want to focus on my work. Maybe this is selfish, but I just want to keep my cycle of life.

Am I strange?
