I would never visit anyone during the festive period without taking some special food treats. A friend who did spend Christmas alone, is off to stay with other pals this evening, she's taking a leg of local lamb, a cheese board, special biscuits and a box of fruit. My sister arrived here for one overnight stay before Christmas, laden down with a cake she'd baked, two great bottles of wine and a lovely bunch of flowers. Hospitality, love and generosity of spirit matter always but imo, especially at this emotionally charged time of year.
As for step grandchildren - I know hardly anyone who doesn't have adopted/step/children who just came for the weekend and never moved out etc etc, within their families. this is almost 2016 and it's the way things are.
I do hope everyone who was alone for Christmas has found some cheer on gransnet or in other places
