Bluetooth, Meet Your Great Great Great Grandfather

(I am working at an office where we are allowed to listen to music. While I am not that tech-savvy, I know more than the average coworker, so they often come to me for tech-questions first. I am in my late-twenties.)

Coworker: *in her mid-twenties* “[My Name], can you help me with the radio?”

Me: “Sure, I can try. What’s wrong?”

Coworker: “Well, this stereo has an option for ‘phono,’ but when I push it, it won’t connect to my phone. My phone can’t find it.”

Me: *staring, until realising she is not joking* “’Phono’ stands for ‘Phonograph.’ It’s so you can hook up a phonograph system?”

Coworker: *blank stare*

Me: “Like, a system you can play an LP record on?”

Coworker: “Oh… OH!” *catching on* “Wow, this system is really old, then!”

Me: “I suddenly feel very, very old.”
