Learning push/pop in the context of a stack provided me with a lifelong justification for being what others call "flighty". This is super evident while doing chores and I jump from washing dishes to wiping counters to washing floors to putting laundry in the washer. To someone at that point it looks like I've started a bunch of things that I didn't finish.

In fact, I paused on the dishes so I could clear a spot on the counter for them, realized I swept a bunch of crumbs on the floor that I needed to clean up, but before I could finish the floor I had to do something with that dirty pile of laundry that was in the way. Keep watching and you'd see me "pop" each of those tasks back off the stack in turn, eventually getting back to the dishes where I started.
