My siblings are... unique. We can go with that.
One of my sisters used to say "PAUSE THE CAR! PAUSE THE CAR! I NEED TO GET BUCKLED" and another one when she was eighteen months old would say "DO IT SELF" and get buckled herself.
Also, side note, @The Wandering Wizard for some reason before you even posted here I knew you were an oldest sibling. You just give off that kind of vibe, I think.
