Putting The Relation Into Relationship, Part 7

(I am a girl. My brother and I are only a year apart, but look very little alike. Despite this, we are close friends and hang out with the same crowd. My brother is driving a new friend and me to a get-together at my dorm.)

Security Guard: “Names and ID?”

Me: “I’m [my name], he’s [my brother’s name], and he’s [friend’s name].”

(The guard waves us in.)

Friend: “Oh, you guys have the same last name.”

Me: “Yeah. I’m his older sister.”

Friend: “…oh.”

Brother: “You didn’t know we were siblings?”

(Our friend suddenly looks very uncomfortable.)

Friend: “…no.”

(It dawns on us that our friend thought my brother and I were a couple.)

Brother: “No. No. No. No. No. No. NO!”

Friend: “I’m sorry!”

(I am laughing too hard to speak.)

Brother: “NO! NO! NO! NO! NOOOOOOOO!”
