My Pet Dream

I never have pet. I wish to have a dog when I am a kid, but my mother was not allowed. She said she have no time to entertain and take care for a pet. I was curious at that time, isn't me the one who take care for pet? Why mother said she will be the one take care them? Of cause, now I understand why. haha..How a 7 years old girl will know how to take care the doggie? I think I might feed the doggie with rubbish rather than Premium dog food.
