An Age Of Confusion

(Three of my siblings are over seven years younger than me and I have a hard time keeping track of their ages. One of them is sulking over something stupid.)

Me: “[Sister], you’re eight years old! Just get over it!”

(My sister looks up, glares at me, and uses her hand to motion ‘up.'”)

Me: “Nine?”

Sister: *repeats hand motion*

Me: “Ten?”

Sister: *repeats hand motion*

Me: “Eleven?!”

Sister: *repeats hand motion*

Me: “Twelve?!”

Sister: *puts her hand up to motion me to stop*

Me: “When the heck did you turn twelve?!” *pause* “Just how old am I, for that matter?!”
