You look over to see a parent driving two kids to the local school. "Sorry Mrs. Robin, maybe later, 'i wish I was the parent in the car'" and you black out along with the (thankfully) slow driving parent. You awaken with your new head on the steering wheel and with a bunch of yelling happening behind you, "great, now I just have to grab the ring and head out of here" you step out of the car to the confusion of the backseat children and rush back over to the now awakening body of Mrs. Robin, "Sorry miss, but I need that ring" you say as you swipe the ring of her finger and place it on your own. "What's going on?! Why am I Mrs. Robin?!" you hear her say from behind you as you walk back to the car and lock the car door behind you then kick the acceleration.
You make it to the local school and the kids behind you get out the car and say, "thanks mommy! Jeez, why was she driving so fast?" You scoff at them "well screw you kids, I won't even be your mommy in a few seconds". You look at the ring and will yourself to become Mary so that she could be out of the way when you swap with Mrs. Robin again.
