Had A Prior Engagement

(A friend has excitedly posted on Facebook after her long term boyfriend proposed.)

Friend: “Oh, my god! He’s finally proposed” *posts picture of her gorgeous ring*

(We all congratulate her. Later she posts that another of her friends has complained about her posting on Facebook.)

Friend: *upset* “I apparently rained on someone’s parade. How dare I post about my engagement on someone’s birthday; it was supposed be HER day not mine.”

Me: “Maybe next time she should give [Fiancé] her diary so he knows when to propose or make any important plans on HER days…”
