Anybody who has a sibling just knows. They know what a certain look means when their brother looks at them from across the room. They know that moment when their parents are about to explode on them and if the sister looks at them they're going to burst into uncontrollable laughter. They're very familiar with that moment when you're minding your own business and then your sibling comes in to annoy tf out of you. It's truly a beautiful dynamic, this thing siblings have. The funny part is, that this kind of family relationship seems to be the same across species! People with sibling pets know this for fact. A cat will sneak up on their unsuspecting canine brother just to jump scare him. A feline will be taking a catnap in their doggo sibling's bed, and the dog will straight up go in and sit on them. If you have a sibling, then you have never related more to animals. Oh, and happy National Siblings day!
