I am retired and have been a widow for several years. My kids are grown and spread out from coast to coast! I often travel to visit them or other family members. Also love my timeshare in Kauai and Princess Cruises!
When I'm away I'm happy to rent out my house so that others can enjoy the wonders of the Bay Area. (The exrtra money helps, too!)
When I'm home, I'm happy to have my downstairs guest room/bath become a bed and breakfast for folks who don't mind sharing the kitchen and living room with me!
