Purposefully Purposeless

I couldn't let my only post today be primarily about masturbation so I'll make this a quick one for the road.

Say you're always honest, always tell the truth, and the minute you know something for certain you are open and upfront about it. Now say you suspect something, you can't be sure, but you're getting more and more sure and more and more scared by it everyday. What's the honest thing to do? Talk about it even though you're not sure? Possibly hurt people because you're almost certain? Or keep it to yourself until your certain? Save the damage till you know it must be done?

Or is the entire question really just a cop out to avoid having to say something while still keeping up the pretense of honesty?

Damn...I need a drink.
