Let's read a short story about Christmas lights!
The Flashy Christmas Tree
Tom decided to decorate the tree with blinking Christmas lights, but he didn’t check the speed setting. When he plugged them in, they flashed so fast it looked like a disco party.
His neighbor Mark was really jealous, so he spent an hour carefully wrapping lights around the tree, only to find they wouldn’t turn on. Frustrated, he checked every bulb. Just as he was about to give up, he found a hidden switch. They were just turned off.
