Two Truths and a Lie

I'm jumping on the bandwagon since I'm franticly packing to go back home for the holiday and feel like I need to post something for ICLW other than my welcome post.

My three things are...

1. I have two differently shaped ears which caused the doctors to look into my kidneys when I was born.
2. I graduated high school in three years even though I failed one of my core classes my senior year.
3. Between myself and my two sisters, I am the only one who got their drivers license at 16.

So, which one is a lie? I'll let you know in a few days if anyone was right.

Good luck guessing!
