Honest man get hated but he never get doubted.

My past conduct was so transparent and so honest that when my enemies spread rumours about me nobody believed them.

An honest man speaks truth, don't expect him to speak sweet.

Favor the fact, forgive the flaw.

An honest man is a debtless man, he doesn't owe anyone anything.

If you want your lie to be believed then you need to speak thousand truths before you lie.
