We normally have a big family Christmas but for various reasons, it will be just 5 of us this year. It seems a shame not to fill our table and share our food and festive cheer with a few extras who might be at home and lonely. DH/DS all on board & we've had various random houseguests over the years so all quite au fait with welcoming a stranger 
But how do you find people who might be keen to join a local family for Xmas dinner? I'm loathe to publically post on Nextdoor or local SM pages as those sort of posts usually end up with loads of cringeworthy "oh aren't you wonderful" messages which is absolutely not the point, but can't see anyone responding to an anonymous post in case I'm a nutter! . Is there an app that links lonely people with families looking to adopt a granny?! Or any ideas for organisations who might be able to match us to someone (or maybe even a couple/family - we have the space)
And finally, anyone else offered a stranger a place at your table on Christmas day?
