When You Blindly Believe

I am driving with my sister-in-law.

Sister-In-Law: “I wonder what those bumpy things between the lanes are for?”

She is referring to the reflectors that split lanes on the highway.

Me: *Jokingly* “Oh, they’re for blind drivers to be able to drive by braille.” 

Sister-In-Law: *Totally genuine* “Oh, that’s pretty smart! I never knew that.”

I was really glad that I was the one driving.
