Is when your sista lightly grabs on to your cheek and you in return give her a hug.
Then you know she really loves you when she gets a better grip and hides for shelter underneath you. It kinda hurts but not really because it's all about the love.
Holy freakin' hell...you know she really loves you when she uses all 12 pounds of her body to bring your head underneath your body. And jumps up and down a couple times, too! You know you're loved when the pain is so strong that you can't think of a maneuver to get yourself out of this predicament.
Yes, it's all about sisterly love.
