What are you planning to watch on TV on Christmas Day? Watch
Call the Midwife and Mrs Browns Boys (my Nan's favourite) would nirmally watch Doctor Who but as well but that's on New Year's Day this/next year
I am sure Call the Midwife will be something my mum will want to watch having worked in hospitals, and also the Queen's Broadcast is obligatory.
I am sorry that your nan likes Mrs Browns Boys, which in my view is a foul mouthed transphobic 'comedy'.
As for me: Top of the Pops, Queen's Speech, The Snowman, Home Alone, most importantly Eastenders and likely another festive film.
