But That’s How Calendars Work?

(Recently, I’ve been attending a series of presentations given by a coworker who happens to have a cube near mine. Today, I get an email from him that off-handedly mentions him giving a class this afternoon, which surprises me, so I stand up to talk to him over the cube wall.)

Me: “Hey, [Coworker #1], are you doing a training thing this afternoon? I don’t have an invite for it on my calendar.”

Coworker #1: “Huh, that’s weird; it should’ve sent one to you. I’ll send you a new one.”

(The coworker that sits on my other side, who was not involved in this brief exchange, speaks up in the most mocking, condescending voice possible:)

Coworker #2: “What, you can’t figure out where to go without a meeting invite? You need your calendar to tell you where to be?”

Me: “Well… yeah, I didn’t know we had a training session this afternoon. If I don’t have an invitation, I won’t know to be there.”

Coworker #2: “Yeah… well…” *grumbles under his breath*

(I have no idea why it was so offensive to him for me to want to have my schedule written down!)
