TAKE HOME A SMILE
 

Take home a smile; forget the petty cares,
The dull, grim grind of all the day's affairs;
The day is done, come be yourself awhile:
Tonight, to those who wait, take home a smile.

Take home a smile; don't scatter grief and gloom
Where laughter and light hearts should always bloom;
What though you've traveled many a dusty mile,
Footsore and weary, still take home a smile.

Take home a smile -- it is not much to do,
But much it means to them who wait for you;
You can be brave for such a little while;
The day of doubt is done -- take home a smile.
