Two Pair Of Twins & Me

I am Chloe Hilton living with my parents, two brothers and two sisters. My older brother and older sister were born on the same day which makes them twins from opposite genders. That leaves my younger sister and younger brother who are also twins from opposite genders. Which only leaves me out. I know what you're thinking, well Chloe if your older brother and sister are twins and your younger brother and sister are also twins, where in the world is YOUR twin? Well as you can see, I don't have a twin, I was born by myself living in my mother's stomach for nine straight months all alone. It kind of irritates me not having someone the same age as me and having the same birthday. But you know as people say, You never know.........
