You mess with my sister, you're messing with me!

We're not doing anything until I find my sister,' I say

There are certain things we owe our little sisters.

[S]isters could do a great deal for their brothers, if they would.

For a moment we glared at each other, stubborn as cats on the stable wall, full of mutual resentment and something darker, the old sense between sisters that there is only really room in the world for one girl. The sense that every fight could be to the death.

Cultivate a spirit of joy and praise. Not only will you light up your own heart, but the hearts of those around you.
Always look for the good in people. In most cases you will find it.
