Don't just pop out when there is a problem, and solve it shallowly. There is no certain right or wrong in anyone. A runaway girl, a drunkard man, an exam failure, may not be fully wrong. Look what happen in their lives before you judge why they do that. They are also seeking for solution for themselves, they need to get away from their problems until they are capable to deal with them. So why judge? Why constraint?

Some people worry about money, because they are not born wealthy, they can easily lose everything.

Some people worry about relationships, because they are lonely. So what if they have a lot of money?

Some people worry about statuses, some worry about future, some worry about entertainment...

Nobody is wrong to worry about different things. It is their environment that forced them to worry about what they don't have.

So don't judge. They ain't killing or destroying other people. They did not hurt other people literally. Trust them, give them confidence.
