Got my husband a light-up Star Wars advent calendar this year (he’s 29). He’s never had a chocolate one, his nan always used to get him card ones, I didn’t even know they existed.
Once when my Argentinian grandma was over for Christmas, she saw me eating my advent calendar chocolate and asked me if she could have one, I guess they don’t have them over there? Anyway it was one of the hardest decisions I ever had to make as a kid (I gave her the Christmas Eve chocolate after a few moments of deliberation)
