My wife has days when she wants us to "talk about things.”  We were discussing aspects of our future so when it was my turn I asked her: "What will you do if I die before you do?”

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 is so active for her age.
 
Then she asked me, "What will you do if I die first?"

 I replied, "Probably the same thing."
