I have a vegetable garden and every summer I enjoy eating
my own vegetables. One day last summer I picked a dozen carrots. Usually, as
soon as I have picked the carrots, I clean the dirt off them by washing them in
a bucket of water. But this day, as I was getting up from the ground with my
twelve carrots, I tripped (绊) and fell over the bucket. The water spilled out of
the bucket, so I decided to wash the carrots quickly in the kitchen sink. I put
the carrots in the sink, washed them with water, and watched all the dirt washed
away down the drain. The next day, when I was washing dishes, I
noticed that the water drained out of the sink much more slowly than usual. It
drained so slowly that I called a plumber (水管工) to come and fix my drain. The
plumber tried a lot of different cleaners and equipment, but nothing worked. He
had to cut a hole in the floor where the drain pipe was in order to try to find
the problem. While he was cutting the small hole, he accidentally cut the
hot-water pipe. Hot water sprayed over the plumber, onto the floor, under the
refrigerator; water went everywhere. My refrigerator stopped
working because the water had affected the electrical wires. I called an
electrician to come and fix the refrigerator. The electrician had to move the
refrigerator to work on the wires. As she was balancing it, she tripped over the
plumber's tools. She fell down and the refrigerator tipped over. It crashed into
the wall, resulting in a huge hole in the wall. I called a
carpenter to come and fix the wall. In order to repair the hole in the wall, the
carpenter had to tear down half of the entire wall. Meanwhile, the plumber was
still looking for the source of the drain problem. Since the kitchen was in a
terrible mess anyway, the plumber decided to remove part of the floor to look at
the pipe there. In the middle of the floor, he found the problem: the dirt from
the carrots was stuck in the pipe and nothing could go through.
Now I had a sink that did not drain, a refrigerator that did not work, a wall
that was half gone, and part of a floor that was missing. I looked at this
disaster and decided that what I really needed was a new kitchen. Finally, I
called a house builder to come and fix my kitchen. Three weeks later I had a new
sink, a new refrigerator, new cupboards on a new wall, new tiles on a new floor,
and $10,000 less in my bank.
