In The Prime Of Their Relationship

(My boyfriend and I are on the couch watching TV. I have a little OCD and can’t stand the volume on the TV to be anything not a multiple of five. The volume is a little low, so I ask him to turn it up. He turns it to 29.)

Me: *general waving at the screen and incoherent mumbles as I start to freak out*

Boyfriend: “It’s okay. 29 is a prime!”

Me: “Ah! Yes! That works!”

Boyfriend: “Yeah, I used to not be able to do anything but fives until I figured out the prime thing.”
