My sister is 18 months (a year and a half) younger than me. There were times in my life when I counted this as a blessing and times when I seriously contemplated throwing her out of the car when we driving down a highway. She has served as my best friend, and my worst enemy and I wouldn't trade her for the world. If you have a sister that's close to you in age you know exactly what I am talking about and have probably had similar experiences of :

1.Your face when you wake up last and miss getting to the bathroom first in the morning before school and are forced to wait until she finishes showering, drying, dressing, painting the mona lisa, and finding a cure for cancer before you can brush your teeth.

2. Two girls in one bathroom = a lot of hair down one shower drain...

3. Sometimes your friends become better friends with your sister than with you.

4. On nights when you're bored you always have someone to hang out with

5. You know you can count on her when things get tough

6. When you hear someone say even one negative thing about her

7. When one of you moves out you have to get used to actually calling each other of you won't speak for months

8. When she has a boyfriend you don't like

9. Getting to have someone on your side when talking to your parents

10. When you finally get through the horror of growing up and actually start to appreciate your sister
