Overhearing How They Are From Others

Why do some people hold grudges,
And maintain negative attitudes...
Towards others who may not remember them.
Or may be a close friend,
Of the one innocently victimized?

This makes little sense.
But there is a reality of this in existence.
And many people have not met,
The ones they dislike and disrespect.
Just 'overhearing' how they are from others,
Is enough for some to pass their judgements.
