Hi clive, I had a Christmas Day alone a while ago when both Son and Daughter were going to their respective in-laws and if you prepare, you can make it a nice day for yourself.
But some delicious food and treats for yourself, if it's a bright Christmas Day, go out for a walk, then eat, drink and sing along to Christmas songs on the radio and watch films and Christmas programmes all day, snuggled under a cozy throw.
And don't forget the Gransnet Christmas party!
