Don't Let the Horse Run Away with Your Apple Cart

There is an old idiom (expression) first recorded in 1788, 'Don't upset the apple cart.' An apple cart was a small open wagon, similar to a wheelbarrow, but much bigger, and could be pushed by hand, or sometimes pulled by a horse. And, of course, it would be piled high with apples. With me so far?
Now, for any of my friends from the Library who are struggling to learn English, please remember: if you have difficulty with any of these crazy blog entries or posts, take notes, and then when we go back to the Library, please feel free to ask me any questions you like. You can also email me at callmejack3@sbcglobal.net.
Anyway, back to the apple cart. Now, the word upset can be used to describe physical illness, such as, I have an upset stomach. Meaning you are sick to your stomach, or possibly feel nauseous. Upset can also mean you are emotionally distressed. Something either is stressing you out, depressing you, or making you mad/angry.
Originally, upsetting the apple cart meant you were disturbing or interferring with the 'status quo' (which would be how things usually work, normal everyday activity), or with someone's plans. If you upset someone's apple cart (such as shake it, or bump into it), well, apples go everywhere. I think you get the idea.
We can also have our own apple carts upset. Our 'apple cart' would represent our plans and the smooth running of our lives.
So tomorrow I will write about a couple of my more recent apple cart disturbances. In the meantime (from now until then), don't let your horse run away with your apple cart. Or, in other words, don't let anything upset you too much. And, of course, stay out of trouble...
