I've lived alone (well, I've had roommates on & off all my life) for going on 40 years now, so it's not a big deal to me. My sister hosts a big Thanksgiving and it's been getting bigger. The year her sister-in-law stole (her words) the dinner from her, I skipped and spent Thanksgiving alone. If my sister ups the headcount again I may start skipping, we'll see how the 17-person event goes this year.
Besides, I have my dog, and this year I am dog-sitting her best dog friend, so I'm not really alone :-D
