This is a true story.

My dad and sister went out shopping on black Friday one year. The went to a local mall that was of course packed. They went to drop a couple of their bags off in the car to free up their hands for more shopping. On their way back to the car, a lady who was driving around looking for a spot pulled up next to them and asked

"Are you two going out?" Hoping to nab their parking space if they were leaving.

To which my dad answered "No, we're related" earning some befuddled looks from the lady and some amused Snickers from my sister.
