Introducing.. Proof that there's no way in HELL I was adopted

I'm the one in red and holding white bear. Incidentally the adorable girl to my right is not in any way related to me.

The youngin is my sister of course. I have other pictures where it's more like I'm looking in a mirror. She's holding our loving cat Cappy who was terrified of me probably cause I pulled her tail at the raucous age of 2.

And can you guess which one is my mom? It shouldn't be too hard. She's the adorable blond in the front with the short shorts.
