Try as one may, it is impossible to deny one's nature
One story sounds good until another is told
Fine clothes may disguise, but silly words will disclose a fool
If you don't want to lose, you should wait for the right opportunity
Every man carries two bags about him, one in front and one behind, and both are full of faults. The bag in front contains his neighbors' faults, the one behind his own. Hence it is that men do not see their own faults, but never fail to see those of others.
Once a wolf, always a wolf.
