I spent a good portion of my younger days pondering the central question of life: why am I here? Now in the full glory of post-menopausal wisdom, I can state unequivocally that I have been put on this Earth for two reasons, to humiliate myself and to eat crow. And, impressively enough, I recently accomplished both in one fell swoop.

My tale of karmic payback began some time ago when my mother was entering the twilight of her 96-year-long life. Though my sisters and I were obviously grateful she was still with us, she developed a habit that regularly had us crying out in frustration, “Why didn’t you go before we left home?”

Without fail, the instant we crossed the threshold of any retail establishment, she declared her urgent—and previously nonexistent—need to use the bathroom. And for doing serious business, too; no “piddling” around for her. Her bowels beckoned with such maddening predictability on these excursions that my sisters and I were convinced she was somehow doing it on purpose to drive us crazy, much like her refusing to wear her hearing aids and then accusing us of whispering in front of her.

“Walking into a store is not a recognized intestinal trigger!” I vented to her in exasperation. “It’s not a thing!”

To expedite the bathroom treks, my sisters and I memorized the layout of every nearby mall, shopping center and superstore with the diligence of thieves planning a heist. Even so, my mom could still throw us a curve ball, the most notorious of which became known as the gas station wino incident.

One afternoon an unexpected road closure landed us on a seedy stretch of highway with our gas tank edging close to “E.” We kept our eyes peeled for a gas station among the mostly abandoned, graffiti-splattered buildings, and finally spotted a dilapidated, but open one. My sister pulled into its littered lot. Our plan was to get in and out as fast as possible, pumping just enough gas to make it back to civilization. My mother’s digestive system had other plans.

“I need to go,” she announced decisively, insisting–over our loud protestations to the contrary–that this place didn’t look so bad.

There was no reasoning with her, so in a desperate attempt to convince her of the unsuitability of this spot, my sister pulled around to the back of the building. She got out of the car and dramatically pulled open the rusted-through door to Exhibit A, thereby exposing the wretched wasteland of a bathroom, as well as taking the drunken vagrant lying in the middle of it—complete with a bottle in a paper bag—quite by surprise. (Despite his surprise, he was rather cordial, you know, in an E. coli carrier kind of way.)

We high-tailed it out of there and sped off down the highway, with my mother shouting the whole time about how we should have just offered him a couple bucks to vacate so she could have used the facilities. Seriously.

My mother has been gone more than four years now, and it turns out the joke is on me. In addition to some of her lovelier qualities, it appears I have also inherited my mother’s unattractive habit of, well, as I’ve indelicately termed it, “retail pooping,” And despite what I formerly believed, it actually is a thing, according to Google. And I have it.

Name the store and I’ve probably used their facilities. From Target to Home Depot to El Corte Inglès in Madrid, I have made a beeline for the bathroom within minutes of entering. At first, I tried to pass it off as coincidence and my husband insisted it was psychological.After the latest incident, however, I can no longer deny the force at work—it’s karma, all right. Super-sized karma. With fries.

I was on my way home from work last week when I suddenly remembered I needed candy for an activity the next morning. I’d already passed the supermarket, so instead of backtracking, I decided to make a quick stop at the rather rundown dollar store up ahead. In the sixty seconds it took me to enter and walk to the candy aisle, the store worked its laxative magic on me with a magnitude too great to ignore.

Panicked, I ran to the back, praying a rest room would be there, while also mentally preparing myself for sanitary conditions several notches below a Walmart bathroom on Black Friday (which I’d actually once experienced). I whimpered in pain upon seeing the “Out of Order” sign on the women’s room door. Directly across from it was the empty men’s room, and my roiling intestines left me no choice but to duck in there. Fortunately, it was a single, but unfortunately, the lock was broken and the door was too far from the toilet for me to hold it shut with my hand or even my foot. So, there I sat, retail pooping in a rundown dollar store men’s room,just waiting for a wino to burst in and complete my humiliation.

They say your poor decisions, such as losing patience with your elderly mother and her irritable bowel, come back to bite you in the butt. Karma knew just where to find my butt, parked atop a dollar store toilet, and it surely put the bite on me. And I know my mom was laughing about it all the way from heaven.
