Teacher's Accidental Regression

 "Good morning, my dear little ones! I hope each and every one of you is having a splendid morning. Today, we embark on a grand artistic adventure with our paintbrushes, although, if the fancy strikes you, finger painting is just as delightful."

"Miss Collins, look what I've created for you! But, I seem to have encountered a bit of a dilemma. Would you be so kind as to lend a hand?"

"Of course, Sammy, I'm here to assist. But first, let's gather around for our captivating storytime. Afterward, we'll savor a delectable snack, and I solemnly swear that I shall lend you my expertise, post-nap."

"Oh, alright, Miss Collins. What enchanting tale awaits us today?"

"Why, Sammy, today's narrative shall be 'The Little Engine That Could.' I've chosen it so each of you may discover that with unwavering determination, you can conquer any challenge that comes your way. Now, everyone, gather round the story rug, and we shall commence our adventure!"

"Miss Collins, Miss Collins!"

"Yes, Tommy, what's on your mind, my dear?"

"Miss Collins, Mike had a little accident. I reckon he's still a wee babe who ought to be in diapers instead of big boy underpants!"

"Now, Tommy, let's not be unkind to Mike. Accidents can happen to anyone, and if you recall, another young lad had a similar mishap last week!"

"But, Miss Collins, I'm doing so well! My mom even called me her 'big boy' now!"

"I understand, sweetheart, but some children require a bit more time to master certain skills. Now, let's return to our story. Did everyone enjoy storytime? Now that we've savored our snacks, it's nap time. Come along, Mike, let's get you cleaned up!"

"Miss Collins, don't forget about my painting, please!"

"Fret not, Sammy. You go ahead and enjoy your nap; I shall work on it in the meantime!"

*Several minutes pass*

"At last, everyone is resting peacefully. Time to assist Sammy with her splendid artwork. Oh, what a marvelous piece it is! She's painted a little girl with my name on it. Now, let me make a few finishing touches here and there... Wait a moment, why is this paintbrush becoming harder to grip? Oh dear, I suddenly have an urgent need to use the restroom. But why did I just say that?"

"Miss Collins, is that really you?"

"Yes, Sammy, it's me. But how did you grow to be as tall as I am? Um... Sammy, pardon me, I must use the restroom immediately. Oh no, I must hurry; it's becoming increasingly difficult to hold it in!"

"Miss Collins, you've fixed my painting! Thank you. Um... Miss Collins, what are you doing?"

"Ha-ha! Look, everyone, we have a new arrival. Miss Collins is standing there, wetting her pants!"

"W...what? No, that can't be! I'm a grown-up, and I'm your teacher!"

"Miss Collins, Tommy's right; you did just stand there and have an accident. But don't worry, I'll assist you, just as you helped me with my painting. Remember, as you said, some children take longer to master certain things!"

"B...but I'm the teacher, and this isn't supposed to happen to me. Why is this occurring? I don't want to wear wet clothes, and my mommy will be so disappointed in me. She might even put me back in diapers until I'm completely potty trained like a big girl. Um... Sammy, will you be my friend, please? I don't want to be teased!"
