You're trying to remember what you had done when suddenly one of your parents walk into the room. It's your mother. Like you, she's completely naked. Of course, that's normal so you don't even register it.
"Hurry up!" Your mother called to you. "Get upstairs and out the door right now, you're going to miss the school bus."
While you don't remember clothing, you do remember being an adult, and the fact you graduated school a long time ago. Now you'd be heading to kindergarten. That certainly wasn't right.
Still, a day at school would probably be a lot more fun than a day at work, but on the other hand you had been happy to finally be old enough not to go to school when you graduated high school. Then again, kindergarten wasn't high school so wouldn't be nearly as miserable.
Your mother had gone back upstairs already, and was waiting on you up there. It was likely you only had a few minutes before you'd miss the bus so you needed to make your decision fast.
