Нельзя произносить вердикты чужим детям по первому впечатлению

We often see a child who is inept and lacks musical ability and realize that all is hopeless. But that's the impression of an outsider, and we can only speak for ourselves. Their mother knows them better and understands their potential. In our cases, it's the teacher who's there instead of the mother. Even if a student brings this up on an exam, their grade is lowered, and they're told of shortcomings that need to be addressed, but they'll never be told they're dumb or stupid. You all know that very well.
