Take time to notice,
What an attention given to others does.
So many unaccustomed to getting it,
Perceive with a belief it is theirs to stay...
And with a permanence.
People like this can sometimes be obnoxious.

Yet there are those who know how fleeting,
An attention given to them gets.
And with a thankfulness they remain gracious,
Not to fret or become upset...
With an acknowledgement whatever they've done,
In time everyone forgets.

Lawrence S. Pertillar
