i want to buy a dog.

When I was a little girl,I liked dogs very much.I had a dog just once.My father bought it for me.

It's name was "Huzi".

It is a Chinese word for tiger.

I liked it very much.

When I went back returned from school, the first thing I would do was to hug Huzi .

It grew up quickly,and became a big and beautiful dog. Or a beautiful big dog (compound adjectives)

But, it passed away as quickly too . I cried  over it for a long time.

After that, I never have the chance to own a dog, and now I am too busy to have one. 
 
Yesterday , on my way to home,I saw a man was selling dogs.

it is There was a beautiful little Labrador retriever(puppy).

It has soft yellow fur and big eyes.

The weather was very cold, but i standed I stood there for a long time, staring at that lovely dog.

I was thinking of buying it and bring it home to buy it home.

My heart is very contradictory.at last i gave up.

My mind had contradictory thoughts , and finally I just gave up on the idea
 I am still regreting it for that now.

Notes : Always start a sentence with a capital letter .and i is always I
