Are you a responsible pet owner?
That's what a guy on Twitter is trying to find out when it comes to his sister. You see, he replaced his sister's goldfish... with carrots... just to see if she'll even notice. Well, by the time this post was written, it has been over 3 days and she STILL hasn't noticed.
In case you're wondering what happened to the goldfish, well, they're in a safe place until the sister realizes that her "fish" aren't swimming anymore.
