My children's story -- Puffy's grave

My daughter's hamster, Taro, died seemingly without any reason. Together, all my
kids dug a hole, in my backyard, as a grave for the hamster. They also
put flowers and tree leaves on the grave. My older son found
a piece of wood, engraved some of words on it and put in front of the grave:

Here lied hamster Taro,
Love
xxxx, xxxxx, xxxxx

My daughter asked for another hamster. My co-worker gave a rabbit Puffy to her
before we went to a pet store. That night, I saw my two boys go went  to backyard
with shovels and dug a bigger hole next to Taro's grave. " What are you
doing over there" I asked.
"We are preparing a grave for the Puffy" answered my older son.
