Bonus question of the day, Inspired by tammy B

This bonus question I am asking was inspired by the blogger Tammy b from
https://tammysreadinglife.wordpress.com/2019/12/20/blogmas-question/

She asked the same question on her blog! If you don’t follow Tammy I highly recommend you go check out her blog!
So what is the question?
