A debt collector is approaching a debtor's house to collect the
debt. He said, "Tom! Its time to pay back the money!"
There is only silence... However, he noticed a pair of shoes
belonging to the debtor outside the licked door. He shouted, "I
know you are inside! Your shoes are out here! You cannot deny
that!"
There is a reply from behind the door, "No I am not inside. I can
walk out barefooted..."
