Bia (my daughter): Daddy, can we have a cow at home?
Me: The cow is too big to leave at home.
Bia: Oh, but she can stay outside.
Me: Well, then we are going to loose her, she would walk away.
Bia: But she can stay in a bird cage.
Me: I don't like birds in cages, or cows for that matter...
We end up releasing the pet and taking a picture of its first flight.
