Lemons need our help.
For generations, we've named our faulty cars and appliances after them, a metaphor for a bitter experience or a general state of disappointment.
I don't know about you, but I've never met a real-life lemon that caused anything but squeals of joy; the aroma and flavor brighten up even the most uninspired dishes, everything from fish to salads to yogurt cake. In high school, my friends and I rubbed cut lemons on our hair, to add highlights. (It worked. Sort of.) Lemons never let me down.
So, I propose we let lemons off the hook. No more negative connotation, no more Peter, Paul and Mary tunes. From now on, when I end up with a toaster that always burns the toast, or a lawn mower that doesn't mulch, I'm going to call it a cauliflower, because that's what personifies a bitter experience for me.
