Don’t Wait Until Flowers Fade
Each spring brings a new blossom of wildflowers in the ditches (路沟) along the highway I travel daily to work.
There is one       blue flower that has always       my eye. I’ve noticed that it blooms only in the morning hours, and the afternoon sun is too warm       it. Every day for approximately two weeks, I see those beautiful      .
This spring, I started a wildflower garden in our yard. I can look out of the       window while doing the dishes and see the flowers. I’ve often thought that those lovely blue flowers from the ditch would look       in that bed alongside       wildflowers.
Everyday I drove       the flowers thinking, “I’ll stop on my way home and dig them.” “Gee, I don’t want to get my good clothes       ...” Whatever the reason, I never stopped to dig them. My husband       gave me a folding shovel(铁锹) one year to be used for that      purpose.
One day on my way home from work, I was       to see that the highway department had moved the ditches and the pretty blue flowers were gone. I thought to myself, “Way to go, you       too long. You       it when you first saw them blooming this spring.”
A week ago we were shocked and saddened to learn that my oldest sister-in-law has a terminal brain tumor(脑瘤晚期). She is 20 years older than my husband and      , because of age and distance, we haven’t been as      as we all would have liked.
I couldn’t help but see the       between the pretty blue flowers and the     between my husband’s sister and us. I do believe that God has given us some time left to plant some valuable       that will bloom every year for us.
And yes, if I see the blue flowers again, you can bet I'll stop and       them to my wildflower garden
