[ WP ] Two strangers accidentally swap carts in a grocery store .

So, it's not merely a story about two strangers who swap shopping carts but a twist on an old horror story. 
 My mum and I were in the supermarket many, many years ago in a country far away. I was pretty excited for some reason about getting meat. Mum told me that she was n't buying meat on that particular day.'Yeah, whatever,' and turned away. When I turned back she'd put meat in the trolley. Triumphant, I yelled at mum'See? You DID buy meat!' Only trouble was, when I looked up, it was n't mum and it was n't her trolley. Some little old lady was standing there staring at the ill-mannered child. 
 I did n't know where my mum was. It turned into one of those trawling the aisles for my mother expeditions to the supermarket that I so love to hate. 
 
 *edit* I have not read the rules and I'm too shamefaced to delete this post. Reddit will remember.
