Whenever you share you'll plead you'll know

The story:

I used to listen to that song a lot on the radio. I even sang those
words out loud in front of others! Thankfully nobody every
seemed to notice. Either that or they could understand the
words to the song either. I always thought it was a strange line,
I mean, 'whenever you share you'll plead you'll know??!!" What
the heck is that supposed to mean anyway?? (considering I'm the
one who heard it that way it probably means I'm nuts!) Then
tonight I was going through the backlog submissions on this site
and found the real words to the song. I am sooo glad nobody
ever really heard my words to the song -- at least until now!
