I recently took my 92-year-old dad to the mall to pick out some new shoes. It was one of those rare outings where I could spend a little quality time with him, and I could tell he was looking forward to it. My dad’s always had a strong independent streak, and though age has slowed him down, he’s still remarkably sharp. Getting him new shoes wasn’t just a necessity; it was an event.

We picked out a nice pair of sturdy shoes that he approved of—a process that took longer than expected as he inspected every aspect, from the soles to the laces. He wouldn’t settle for anything less than “sturdy enough for a hike but classy enough for church,” as he put it. Once we had his new shoes sorted, we decided to make a bit of a day out of it and headed over to the food court for some lunch.

We found a spot and ordered some sandwiches. While we waited, my dad leaned back in his chair, looking around. The mall was bustling with people of all ages, from toddlers clutching their parents’ hands to teenagers strutting around in their own worlds. I could tell my dad was observing them all, as he often does, soaking in the scene with a kind of calm curiosity.

As our food arrived, my dad’s attention drifted to a teenager sitting a few tables away. The kid had hair styled into wild spikes, each one dyed a different bright color—green, red, orange, blue—you name it. It was quite a sight. My dad, clearly intrigued, kept glancing over at him. It was hard to tell if he was amused or just fascinated, but every time the teenager caught him staring, my dad quickly looked away, only to sneak another glance a few moments later.
