I find it interesting sometimes that even the most ordinary occurrences can have an impact on our awareness.

My wife, daughter, and I moved into our home nine years ago and we ______ a lot of time and energy in the yard to getting it looking like it does today. We ______ on a corner, higher than street level, and the entire side of the yard is ______ by a professionally built rock wall. We did the best to put what we had into ______ and called this area our “rock garden”. Whenever we had flowers or plants, my wife Denise or I would stick them out and plant them in the “rock garden”, just to bring some ______ to the area.

I still do all of my own yard work, even the ______ weed-pulling. After ______ my knee pads, I assume the ______ to clear the yard of weeds, even in the rock garden.

Last summer I had reached the end of the rock garden and found a tiny little ______ that I could not ______ identify. I knew I didn’t plant it and Denise ______ that she didn’t either. We decided to let it continue growing until we could ______ what it was.

Weeks passed and ______ I made my way back to the mystery plant, it appeared to be a sunflower. It was ______, looking with a tall thin stalk (茎) and only one head on it. I decided to ______ it and weed around it. As I ______ rocks from the area to get to the weeds, I noticed something ______. The sunflower had not started where I saw the stalk begin. It actually had begun under a big rock and ______ under and around it to reach the sun.
