I'm just wondering around these days.. Why do i have some friend that know myself even better than i do?

The first reason why i thought like that is..

My class is having mini-footbal cup these days.  (re: futsal) when i want to join that as a player, my friend said that,

"don't be afraid of the ball when we're on the field later!"

Woah. Speechless.. I think i never told her that i'm afraid of the ball. But i still think that maybe i could be some help then.. Actually, we've never play football together too. But she already know that i'm kinda afraid of it.. I'm asking, how come does she know about it? :/ hahaha

The second one is....

I don't know what to tell, just think that my friend can look through myself better than i do..
