Dirt on the window

   Man does not wear colored glasses

  to have a wife over the years complained opposite the woman too lazy: "The woman's clothes never wash clean, look, her clothes hanging in the yard, there are always spots, I really do not know, Why does she even wash her clothes like this?" It wasn't until one day when a careful friend came to her house that she realized that the woman who was not the other side was not washing clean. The friend picked up a rag, wiped the dust off the wife's window, and said, "Look, isn't this clean?" It turned out that the window of his house was dirty.

  The windows are dirty, so everything you see is stained. We are accustomed to examining others with critical eyes, but we ignore our own problems. Don't be anxious to beg others in advance, and instead seek out others. Finding out the reasons from yourself is the better way to solve the problem.
