Morning, but we don't have a chocolate one.
This year ds has a Playmobil one - the police one, which I have just finished assembling.
He and I also each have one with pictures in, and we have an annual competition, where we guess what is going to be in the picture for each day. If we get the correct item on the correct day we get 2 points, and if we find an item we have guessed but on the wrong day it's 1 point. Last year ds won hands down due to the crap pictures in my quirky nature of my advent calendar, which my sister had sent me. Hope she has selected something with better pictures this year!
