Joyce's memory association

Mr Neil asked us to write a personal recount/memory association on either the words, tree/pet/water. I chose pet. Whenever I see fishes, I will always remember the time when i had a guppy. But sadly, it died...
I remembered when I was 5 years old, my grandfather gave me a guppy for my birthday present. I was very excited as that was the first time I ever had a pet. I prepared the aquarium together with my mother, and we poured a lot of water into the huge aquarium. Then, carefully, we placed the guppy into the aquarium. Lastly, we observed it for a while and the guppy started to swim about freely in the water. My mother and I were very excited as we finally had a pet of our own.
From then on, I took good care of the guppy and observed it whenever I had free time. But sadly. one day, when I came home from school, I found it floating upside down, with its stomach facing up. I would always remember this pet as it was my first pet and it brought me lots of joy.
