Story 15/7/2014

Every day, there was an old man who drove a motorbike across the border from Canada to America.
This piqued the border officer's curiosity.
One day, the border officer stopped the old man and he asked, "What do you have in your haversack every day?" The old man answered, "It is just sand."
The border officer did not buy his story. He examined the old man's haversack. It was indeed just sand.
After a few days' more inspection, the old man's haversack was always filled with sand, just the sand.
Curiosity killed the cat. One time, the border officer decided to get to the bottom of the mystery. He blocked the old man again. He asked the old man, "Be honest, are you smuggling something? please tell me, and I promised I will not arrest you."
The old man replied, "Yes,"
"What do you smuggle?"

Hi, do you know what kind of things the old man smuggle?

How to use "Everyday" and "Every day"?

Right then, it's a classic story, this one. I've heard versions of this with wheelbarrows and donkeys and now with a motorbike. The man is not smuggling the normal, everyday sand that he had in his bag every day, but he was smuggling...

...motorbikes!

It's a good story and very well written. My only big correction is that the proverb 'curiosity killed the cat' means that 'curiosity is dangerous'. It is used to warn people from asking too many questions or from investigating things too much. Personally, I hate the phrase 'curiosity killed the cat' because I believe people should ask questions and investigate things. This is one of the best of human characteristics, our curiosity for more learning. So, you used it in the wrong way, and when people use it in the right way, it 'sets my teeth on edge', as we say.

Oh, and usually in English, we start a new line when a new person speaks, so as not to confuse the reader as to who is speaking, so I corrected that too.

Good use of the phrase 'piqued the curiosity', by the way. People don't use that phrase every day, as it is not an everyday phrase, but it always sounds nice when I hear it. Very good.
