Pickles are not something that I grew up with in Sri Lanka. They were a new food I encountered only once I came to the US and I found that I do not like them at all. When I find them in food, I carefully take them out before eating unless I accidentally eat them because they have been cut up small.
But for the longest time, I was not aware that pickles were just cucumbers that had been processed in some way. I had thought that pickles were a separate kind of plant. Then once in conversation with my daughters, I casually said something about pickle plants. After a brief pause of incredulity, they laughed hilariously at my ignorance and I discovered that I had been wrong all this time. I learned later that the word pickle is itself shorthand for ‘pickled cucumber’. If I had known the full name, I would have not been confused.
It makes me wonder what other things I believe that are absurdly wrong but common knowledge to everyone else. And what kind of event will bring my ignorance to the surface.
