What to do???

Sometimes I wonder what to do, when something bad happens to your friend and they do not know that you knew that it happened. Like should you go up to them and talk with them about it and tell them that you are there for them or should you wait until they tell you about it.

You feel like you wanna help them with their problem, but you don´t want to pushed them through a talk, which they might not want. Simply because you know what happened through someone else. Hard situation were there is no right answer to how you should react and how much you should do to help them without making them feel worse about the situation. 

The world is a confusing place, and the right way of doing stuff is something we got through centuries of social communication. It is norms and social conduct that has been implanted into our mind from the moment we are born, which will not change. But even with all our social norms and conduct, we still do not have an answer for what to do, when you face situations like this one. 

The world is what our ancestors made it into and we simply fit ourselves into it and change a fragment of things, simply because someone went against one of our social norms and people decided to follow that person because that person screamed the loudest.
