Should I Tell?

I went to a wedding today
Happiness seemed all around me
But later I overheard the parents of the groom
Saying their love wasn't meant to be
But who are they to say how hearts should feel?
They did not speak up when the Father asked
If anyone present knew reason why this should not be
Only in secret when they thought I could not hear
How sad to think they wait for the end
When two young lovers have just begun in unity
I wonder when their children are born
Will they see things differently?
I wonder if none ever come, will they still be shunned?
What a shame to think this young couple may never know
Should I tell? Should I tell? Should I tell?
