You think you and your sister annoying each other constantly and relentlessly is a unique thing? Think again, because apparently it's not even only a human thing. As clearly showcased by these adorable wolf siblings, wolf siblings too show each other love by annoying the heck out of one another.
This act of head-sitting is no accident either. There was deliberation there, a consideration of the warning given, and a decision to be an annoying sister anyway - slowly and purposefully climbing onto her sister and adjusting her position until she is perfectly situated on her sister's head. Just as any goofy sibling would.
