Go on vacation, lose house

Mel and Harriet went on vacation to New York but when they returned to their Florida home, they found the locks changed, power turned off, and things missing.  They thought they had been robbed but instead it was a bank.  Even though their mortgage was paid off for 15 years, the bank mistakenly claimed it was in foreclosure.  When in fact, they had just gone to the wrong house.  mess
