Fishboy,

We need some protocol here. Only old farts can address other old farts as old farts. We can also address young whippersnappers as young whippersnappers.

Young whippersnappers can only address other young whippersnappers as young whippersnappers. Never address old farts as old farts... bad protocol... and it makes them crotchety. Also elicits the remark of "the younger set isn't the same as it should be".
