How one should behave towards human people?

You imagine that you know people, but you don't.

 

There are people on an understanding of the feelings of others, aren't there?

 

It's so easy to stumble.

Easier to show that you don't care anymore.

Too easy to fail in a duty to warm heart?

 

It's too late to contact beyond the grave.

Don't forget the polite behavior although one trys your patience.
