How difficult do you truely trust somebody?

You may think that you have many best friends.
but so do they?


How can you be sure that you are accepted in your daily social?

someone may act liked you are one of their friend.
have lunch with you, laugh together.
but you may be talked behind liked a fool.

These questions keep running in my mind.
I'm not a 'perfect' man who will be loved by e'one.
do i think too much? am i so serious with life?
may be yes.
but i'm just afraid. i may be betrayed by what i trust.

what should i do?
