Three year old Sherlock accompanies Mummy whenever she goes to pick up Mycroft at school. He is always vibrating with excitement as he watches the students coming out of the school gates while he holds Mummy’s hand and clutches his bumblebee plushie, and happily screams "My! My! My!” as soon as he finally sees his brother.
One day, the school bell rings and Mycroft is about to head out of his class when his teacher asks to speak to him.
The well-intentioned teacher tells Mycroft that he needs to interact more with his classmates. Mycroft politely listens, but this turns into a long lecture and he grows increasingly concerned about his little brother, especially after his ears pick up the faint sound of crying coming from outside. After a few minutes, the wailing seems to stop, and Mycroft hopes that this means Mummy managed to soothe Sherlock. The teacher is still going on about how friends are important, even for one who is as intelligent as Mycroft. . .
Suddenly, Mycroft turns his head towards the door. He thought he heard. . . yes, this is the pitter patter of very small feet, and it’s coming towards the classroom, growing louder and louder.
The teacher stops talking when the door is thrown open, and something flies towards Mycroft like an arrow and jumps into his arms.
"Sherlock!" Mycroft scolds. "Why didn’t you wait with Mummy? She must be very worried right now!" Sherlock being here clearly means that he escaped from Mummy. Not that it would be difficult for her to figure out where Sherlock went - although she will be surprised that his little brother knew where his classroom was.
"I waited and waited and you never came out!" Sherlock cries as he buries his face into Mycroft’s neck. "I was worried! I thought you were dead! Why didn’t you come out!?"
"Shhhh, I’m not dead you little idiot," Mycroft says as he rubs Sherlock’s back. "The teacher just needed to speak with me."
This prompts Sherlock to raise his head. He looks at the teacher. "Did you make Mycroft stay here?" he asks with all the sternness that a three year old can muster.
"Sherlock, that’s enough." Mycroft addresses his teacher. "I’m sorry, sir."
The teacher finally finds his voice again, and assures Mycroft that it’s all right. Truth be told, he’s a little relieved - he’s been concerned about Mycroft’s seeming inability to emotionally connect with the other children, but his student is clearly extremely close to his younger brother.
A few moments later, Mummy, who is out of breath, finally shows up and gathers her two sons into a hug.
