Please Stop Making Me Do Math

I have recently had my second child and am at her “first days of life” appointment. I have also brought along my three-year-old daughter. After the appointment, we go to the front desk to check out.

Me: “Can we also schedule [Three-Year-Old]’s four-year checkup for April?”

Receptionist: “Sure, how many months is she?”

Me: “How many months is [Three-Year-Old]?”

Receptionist: “Yes.”

Me: “She turns four in a few months.”

Receptionist: *Irritated* “But how many months is she?”

I try to calculate.

Me: “That’s not really something I kept track of off the top of my head after she turned two, but she’s forty-five months.”
