Only two came to mind over the weekend. Layered paradox.

No one likes a bragger. My son and his friends were always outdoing each other in the brag fest. Hubs used the Al Pacino quote to discourage bragging and it stuck. The boys were all boasting the various surf maneuvers they were capable of accomplishing. Hubs said "Who do you like better and cheer for? The guy who brags all the time or the guy who keeps his accomplishments to himself? If your really are good, show it - don't spoil it. Don't ever let them see you coming."

Lips moving, still talking...
