According to Thai news site Matichon, Boontom Chaimoon and Amnuay Chaimoon set off on Christmas Day to drive through the night to her hometown in the province of Maha Sarakham, in central northeastern Thailand.
During the trip, Boontom, 55, pulled his Isuzu pickup over to the side of the road so he could urinate.
After he stopped, Amnuay decided she would also relieve herself and ducked into a nearby jungle for a quick bathroom break.
To make matters worse, she had no money or phone on her, so had to seek help on foot.
Thirteen miles later – just shy of a half marathon – Amnuay made it into the centre of Kabin Buri where she found a police station around 5am.
She pleaded with police to help her find her husband, whose phone number she could not remember.
Police located Boontom’s number, but despite calling him 20 times he didn’t pick up. He reportedly didn’t notice as drove on blissfully unaware of the predicament he’d left his wife in.
When he eventually realised Amnuay wasn’t in their vehicle, Boontom was 100 miles away.
He then had to turn back and collect her.
According to reports, Boontom had believed his wife of 27 years was sleeping in the backseat the entire journey.
