If you have a kind word to say, say it now
If you have something to give, give it now
If you can make someone glad or another less sad,
Do it now... Do it now.... Do it now...
If you have trust to bestow, show it now
If you have friendship to give, give it now
If there's pain you can ease or someone you can please,
Do it now... Do it now... Do it now...
