Say that Larry the Landlord is renting out a residence to Terry the Tenant.
Larry gets taken out of the picture somehow (maybe he committed a crime and is in jail for a long time, or maybe he died with no will, etc.).
Can Terry just go on living like a king in the residence without paying rent? If Larry happens to come back some time later (perhaps after finishing his jail sentence), can he reasonably demand Terry pay every last month's rent?
