One minute they're at each other's throats because one child touched the library book that was the OTHER child's choice for Momma to read after breakfast, and while they scream at each other and make "scary faces" (the preferred method of attack, always effective), you think, "What's wrong with them? They're SISTERS. I want for them to love each other more than they love their father and me, to always have each other long after we two are gone, and look at them! They hate each other's guts! They'll fight their whole lives and never be close!"
Then, three hours later, during a picnic lunch at the park, you see this:Sisters.
