Since my 7-month-old is my only witness, you’ll just have to trust me when I say that I raise my right hand, place it over my heart, and solemnly swear to never use the word “jubilee” in any of my writing.

I’m not sure why it gets on my nerves so badly, but I cannot stand this word or people who use it.
