When you started to worry about someone,then for sure you wish to know more about him.
However, I found that sometimes others may not know that...
They may just feel that you're so annoying by keeping asking questions.
They wish that you stop it immediately.
My conclusion is the more you care, the more you get hurt...
You care, then you think. You think, then you will get worried.
When you get worried, then you will try to find out the answer.
When you try to find out the answer, then people will stop you.
When people try to stop you, then they will use something to hurt you.
So that can make you stop.
