It was the second week of school and as usual, Sherlock dreaded getting up in the mornings. He hated school. The building was full of idiots and Mycroft had taught him all the things he was learning when he was four. It was lonely, too. It was alright at home, where he could go into his room and experiment if he needed something to do, but at school it was nearly intolerable to see the groups and best friends and all the people who just plain weren't reviled.
Mycroft woke him up at 8 o'clock sharp, just like every morning through the school year. Sherlock lay in bed for as long as he could and when Mycroft came to get him at 8.45 he kicked him in the shins while Mycroft dragged clothing over his head in a very undignified manner. It was the only thing about the morning he enjoyed.
At 8.55, Mycroft dragged him to the bus stop and stand with him til the bus came in order to ensure that he didn't skip school again to go to the library.
At nine o'clock, the bus came. Sherlock got on it with his backpack and lunchbox, which he never 'forgot' since it was the only meal he consistently ate, and walked to the very back left seat. As usual, no one sat with him.
The bus arrived at school at 9.15. Sherlock arrived at school at 9.20,the driver having been paid by Mycroft to make sure he got to his classes. When he arrived, school started and he zoned out to go to his mind palace.
Lunch and recess were at 12 o'clock. Sherlock ate his half peanut butter sandwich and pint of milk alone, then began to test samples in the dirt, a project he'd started on the second day of school. He was nearly finished, unfortunately.
At 12:23, something new and interesting happened. Phillip Anderson was talking to the new boy (who looked nice and was probably too stupid to think cohesively).
At 12:25, Anderson's stupid girlfriend grabbed the boy's arms and Anderson himself kicked the boy in the ankle. Sherlock almost felt bad, but he felt better when he realised they wouldn't be picking on him for a change.
At 12:26, Anderson unexpectedly drove his fist into the boy's stomach, causing the boy to collapse onto he ground with his arms still twisted upwards, and Sherlock changed his mind. He walked over to Anderson, tapped his shoulder, and gave him a nice black eye. Anderson was shocked for several seconds - no one ever stood up to him! - which time Sherlock used to sweep his legs under Anderson and knock him to the ground. The idiot didn't even start fighting back until Sherlock was on top of him.
Eventually Sally entered the mix, but he had had so much practice fighting against their whole group that he took her easily. The new boy was still lying on the ground. Sherlock snuck a quick glance and hoped he wasn't unconscious.
