Example

On a whim, I bought a red foil balloon at the grocery store. The message “I Love You” streamed across the front in billowy script. As I was loading bags into my car, the balloon’s string slid through my fingers. I stood there watching it float away, and soon it was nothing more than a tiny red dot—finally, just a memory.

My Observation:

There is a “HIM” in the word but leads by a “W”. Interesting!
