A Bad Month For Math

Coworker: “[Other Coworker] is probably retiring soon. I wonder how long he has worked here?”

Me: “He’s been here since 1978.”

Coworker: “How do you know?”

Me: “He’s excited to mark 40 years with the company in May; we plan to have a little party for him.”

Coworker: “Okay, but how do you know that’s 40 years?”

Me: “I just subtracted to figure it out.”

Coworker: *looking confused* “If you say so. That’s a long time. Do you know what day he started?”

Me: “No, just that he said it was in May.”

Coworker: “Can’t you just subtract to figure it out?”

Me: “Uh, no.”

Coworker: “Yeah. I’m bad at math, too.”
