How does my story sound so far?

I was up in the attic, looking for a suitcase. My family was going on a cruise to the Bahamas tomorrow for my 14th birthday and I needed something more to put my stuff in. I stumbled upon an old box, with dust and cobwebs practically suction cupped to it. Written with black magic marker on the front it said Chenille’s Baby Stuff. The box was rather large, and I was rather curious. I opened the flaps on the box and to see what was inside surprised me, pictures, toys, clothes, blankets, basically all my stuff from when I was a newborn. On top I saw a birth certificate. Mine. I looked at it for a few minutes; I saw my name, Chenille Marie Antonio. My birthday was also on there… And everything else that should. Then I noticed something that said multiple birth: twin. Wait a minute… I’m an only child as far as I’ve ever known.
