What do you do if you are asked to deliver a pile of Christmas cards and one of them has an erroneous, nonexistent address on the envelope?

There are teW ways of handling this (btw,I bet you didn't know I was a spelling champ,eh? :)
A-the high road,give it back to the person who sent you on this errand,explaining there is no such address.OR the expedient,lazy way;ie,toss it in the nearest circular file!
If there are any questions later,blame it on the Postman,who never rings twice! :)
