Uh... this app is some kind of odd social hangout where activity generates points that are used to buy other people who have added the application.
You are owned because, at one point or the other, somebody decided to pay 50 points so that they could say that they own you.
Time has gone on, and you've been given away from person to person, and as you've been given farther and farther away, people then have no idea who you are, but thus, "own" you.
I was given you by my friend Kerry, who'd received you from our mutual friend Codey (Though she likes to go by Lunar)
Somewhere along the line you actually decided to add this application.
I totally understand were you're coming from though. I personally always thought this application was a little too goofy. I only joined when my friend said "you should Add the Human Pets App. It would make owning you so much more fun!"
I did so, and was imediately bought up by someone else, to my friends dismay.
Was rather comical actually.
So, who do you think it was that bought you in the first place anyway? I'm actually pretty curious to know the path of ownership you've unwittingly taken to come into my... 'possession'
