many friends come and go,
the best and closest friends stay.
But have you ever thought;
Who's the true friends?
You'll only see their true colours when somethings happens.

I've learnt that the best and closest friends might not necessarily be a true friend.It's not totally about how trustworthy the person is. But also about the amount of trust that you place in the person. It's pretty untrue to say that you can't trust the person at all. And it's not even possible to say that you yourself is/is very trustworthy. Others can't judge you. But neither can you assume what you think you are. You won't know how they see you as cause everybody thinks differently.
