small sisters a big pain

That's the job of younger sisters. They are their to make your life a living hell. Joke! seriously, since they are younger than you, your parents expect you to be more patient when dealing with them and since you are still a kid, sometimes you just don't want to deal with them because of the way they behave. I mean who does?, a kid who sometimes pisses you of, but also remember that they don't really know what they are doing and they don't have a clear view of what is right and wrong.

It's not just the small sisters. Let's also include the younger brothers. I think your situation became my situation way back when I was younger. When my brother did something wrong, I was the one who blamed. If he got low grades my mom will be mad at me because I didn't teach him. What was that! Urgg! It's a good thing we both matured and mom doesn't get mad at me whenever my brother did something wrong.
