Not on the Christmas Eve?
Nope. Christmas Eve is either pub (which closes early) or family.
Earlier in the day, last minute shopping.
In Poland on 25 dec we are laying in beds, watching tv and feeling sick with the yesterday meal
That's what we do on the 26th : )
Other pastimes for this date (although not for me) include drinking all day (the reopening of the pubs) and it's also a big horseracing day.
