After they had retired a man and his wife were discussing aspects of their future.
"What will you do if I die before you do?" asked the man.
After some thought, she said that she'd probably look for a house-sharing situation with three other single or widowed women who might be a little younger than herself, since she was so active for her age.
Then the woman asked, "What will you do if I die first?"
He replied, "Probably the same thing."
