Silent Protest

I won't lie to you but silence would speak volumes
So how should I react to your joy built so poorly on sandy ground?
Do I voice my concern and risk friendship or hold my toungue and let you learn the hard way?
I will support and encourage and hope for the best but if put to the question I'll admit doubt
And most likely you'll justify your reasons, letting me know that I don't know enough to have a say
Even though I've been right so often before
