However, people are always self-protectively. 

That is a common sense when a stranger getting approach to you, but what you may not know is he/she had probably concerned about you for a long time.

Please do not hurt the one who suddenly say the words "can we make friends?" to you cos when he/she speak out that words, he/she had already made a selection. 

I was suddenly suffered from the loneliness, but I am alright. 

Keep straight forward.
