Short words come in handy. In fact, I often prefer them to longer words. But they can also be deceptively hard to read. How about this sentence:
“And it was as if an eon ago, or was it one fun day ago as the sun lit my web log and I was sad to see my eye lid dip.”
Certainly you can do better than that, but only if you can use words with three letters or less. Try it!
