The Substitute Teacher Who Wanted Blueprints of Our House
A fifth-grade assignment took a strange turn when a substitute teacher asked students to draw schematics of their homes. What followed — a wildly fictional floor plan and a priceless reaction from my mom — turned into one of my funniest childhood memories.

The Substitute Teacher Who Wanted Blueprints of Our House
Elementary school memories tend to blend together — cafeteria pizza, playground arguments, the eternal struggle of times tables — but every once in a while, something happens that sticks with you for life. For me, that moment came in the fifth grade during a week when our regular teacher was out, and we cycled through substitute teachers like we were testing models for durability. By midweek, in walked a substitute with a mysterious, slightly intense energy — the kind of vibe that suggested he either meditated at dawn or worked a graveyard shift doing something he couldn’t talk about. We settled into our seats, expecting worksheets or quiet reading time. But nope. He had other plans. “Today,” he announced, “we’re going to draw schematics of our houses.” Schematics. Not drawings. Not little houses with smoke coming out of the chimney. Actual blueprint-style schematics. He wanted the layout of our bedrooms, our parents’ rooms, and where the pets slept. Every detail. Now, to be fair, Highlights Magazine did have a feature that month teaching kids how to draw floor plans. So maybe he was just a bit overenthusiastic about cross-curricular learning. Or maybe — and this is my completely rhetorical adult theory — he worked the graveyard shift as a cat burglar gathering intel between heists. Just moonlighting between blueprints. While the rest of the class tried their best to recreate their actual homes, my imagination sprinted in a totally different direction. The house I drew had:- A massive master bedroom with an oversized bathroom for my parents
- Separate bedrooms for us kids on the opposite side of the house
- A kitchen placed right in the center like a command center
- And the dog — the true VIP — had a luxurious two-story doghouse

What makes a true Santa is inside – and comes with the red suit
Research on 849 professional Santas reveals three types: prototypical, semi-prototypical, and nonprototypical. Discover how diverse Santas navigate stereotypes and why many see the red suit as a calling, not just a job.

What makes a true Santa is inside – and comes with the red suit
Christina Hymer, University of Tennessee When you picture Santa Claus, a white, bearded, overweight and jolly man who dashes around delivering gifts to children during the Christmas season probably comes to mind. Yet, not everyone who dons the red suit fits this stereotype. That’s what Bethany Cockburn, Borbala Csillag and I learned when we teamed up to study professional Santas. For our study, we looked into how these professional Santas were able to “be” Santa, even if they didn’t fully fit the image. As we explained in a forthcoming article in the Academy of Management Journal, many who do this work don’t see it as just a job – it’s a calling. For some professional Santas, it’s especially important that they look and feel like Santa to experience that sense of purpose in their work. We surveyed 849 professional Santas who live across the U.S. and interviewed 53 of them, collecting data between 2018 and 2021. We identified three types of professional Santas: prototypical (64%), semi-prototypical (23%) and nonprototypical (13%). Prototypical Santas look the part. They are white and overweight, have real beards and express confidence that they are the right fit. Semi-prototypical Santas looked the part, too, but felt like they weren’t quite suitable for a range of reasons. They might be introverted or use a fake beard. Nonprototypical Santas had characteristics at odds with the stereotype. They might be nonwhite, female or gay, or have a physical disability.Why it matters
While anyone can take a turn being their neighborhood potluck’s Santa, the one you meet at the mall probably attended some combination of Santa schools, webinars and training. For instance, the Charles W. Howard Santa Claus School was founded in 1937 and conducts an annual Santa training each year. National networks also exist, such as the Fraternal Order of Real Bearded Santas, which says it has 1,000 members, – and the IBRBS, formerly known as the International Brotherhood of Real Bearded Santas, offering meetups and professional support.
What’s next
I’m now looking at how broader institutional environments, current events and social movements can shape how people experience their callings and find meaning at work.
