>You know that someone is a real friend and loves you no matter what when you can be completely honest with them.

So honest, in fact, that when they ask you, “How was your birthday?” you feel safe enough to answer with all the honesty and sincerity in the world, “It sucked.”

Then, when she laughs and said, “Me too!,” you can laugh and commiserate together.

That’s when you’ve got sister kind of love.
