(I have recently moved into my own apartment, and my siblings still live with my parents. I am hanging out at my place and get a call from my dad.)
Me: “Hey Dad, what’s up?”
Dad: “I have a question for you.”
Sister: *in background* “Oh, God…”
Dad: “What is the little snowflake button for in the car?
Me: “Seriously?”
Dad: “Yes.”
Me: “The air conditioning. Why?”
Dad: *to my sister* “Your sister knows what it’s for!”
Me: “She didn’t know what it was for, did she?”
Sister: *in background* “Oh, shut up!”
Me: “Oh man, what happened?”
Dad: *laughing* “She thought it was broken on her brand new car, so she’s been driving around without A/C all summer!”
Me: “It’s been over 100 degrees out! What did she…?”
Sister: *grabs phone from my dad* “I thought it was the defroster. Okay!? Geez!”
