A door found for one to be left open,
Does not mean for them it may close.
To becomed locked.
And the occupant other the other side,
May one day ignore the knocks.
It always pays to respect a hospitality given.
To take it for granted,
Does not mean that hospitality given will stop.
But for that one who takes advantage of another,
A decision will be made to block further entrances.
Lawrence S. Pertillar
