Not as elegant a story, but just goes to show you can find insiration anywhere.
I was in the grocery store and started pushing a shopping cart. Instead of going forward it took a sharp left turn. The thought came immediately, this cart has a mind of it's own.
So.
With apologies to Connie Francis. Tune "My heart has a mind of its own"
At the local grocery store, I found a shopping cart But one of its wheels just wouldn't start although the other three, they all turn left you see Guess my cart has a mind of its own.
I wanted aisle thirteen to buy some baking goods but these wheels, they don't turn the way they should and so I ended up, in personal feminine stuff Guess my cart has a mind of its own.
The butcher fancies me, each tim I pass him by he looks me up and down and winks his eye.
I tell this cart of mine to find the checkout line but it wants to go around just one more time. I've been around this store eleven times or more Guess my cart has a mind of its own.
