Your attitude to others is of your choice
It never does cost anything to be nice
Some spread the glow of joy in their friendly way
With their happy smile as they bid you good day
With what I say here most would surely agree
I do like the people who are nice to me
Why should I like those who try to drag me down
Who would if they could run me out of the town
I do like people who have the inner glow
Nice people are people I do like to know
Those negative to me I'd rather not meet
Their arrogance born of too much self conceit
A smile and hello as they pass on their way
Nice people they help to bring joy to your day.
