Okay, My New Camera....

yesterday, my father bought a new camera. Since my previous camera is broken, so I automatically thought that the new camera is mine. Until one evening.
Mom: where are your old camera's batteries?
Me: Why? Just let me charge them and fill them.
Mom: I want to do it now, cause I must bring the new camera tomorrow.
Me: WHY? I want to play with that new camera!!
Mom: It's mine, honey. It's for me.
Me: WHAT THE?! You already have your own camera!! YOU ALREADY HAVE!!
Mom: It's heavy. I want a light camera to bring to my office everyday.

(in fact the old camera, a Kodak, not that heavy. She just wants to use a new Sony I assume)

Me: So the Kodak is mine now?
Mom: yeah.
Me: Does it still work properly?
Mom: yes.
Me: okay.

just wondering why my mom is as selfish as I am.
