considering she works in retail, they spam the same few christmas songs for hours, and all the customers talk about christmas, all her co-workers will talk about what they're doing for christmas, everything in the store is based around some christmas special, the store has special christmas decorations, and over priced special christmas shit to sell to morons
then she goes home to dave who is wearing a christmas sweater and pyjama pants, talking about his christmas marathon, christmas movies, 8 bit christmas songs
then he expects her to cuddle with him on the couch after she cooks HIS favourite christmas meal, demands to watch HIS favourite christmas cartoons
