It's the week before Thanksgiving 2017, and there's a childless woman in Arizona who isn't looking forward to the holiday. Perhaps her story sounds something like yours.
Abby's brief response, in my option, was textbook. "Choose a different destination each year to visit and learn about", she wrote. Invite some friends or acquaintances to join you at home."
At our house, Andy and I have luxurious memories of hosting Thanksgiving and Christmas Eve dinners with as many as 16 family members and friends. I can get lost in those memories, and that's not really a good thing, now that all of those people are gone. Both family and friends have died, relocated to assisted facilities or moved to another coast. Meanwhile, we're still unaccustomed to today's reality.
(There's a skill to visiting a memory and leaving it the heck alone. I don't quite have it perfected.)
