Sans and Papyrus' childhood (mainly Sans')

(The image above is depicting Papyrus who punched himself in the face to give himself a bruise to make Sans feel better about being attacked by the Anti-mental health kids again)

"SANS!" Papyrus beated on the door "YOU CAN'T HIDE IN YOUR ROOM FOREVER!" 

"Why can't I be home schooled?" Sans called back

"Beacuse Mommy is too busy and Dad isn't the best teacher!" Papyrus responded though the door then whispered to himself "and disabled.."

"BUT EVERYONE HATES ME!" Sans yelled and barricaded the door 

"SANS C. GASTER, I'LL GIVE YOU UNTIL THE COUNT OF THREE TO GET OUT OF THERE!" Papyrus ordered but Sans already escaped through the window

"One... two... THREE!" and Papyrus busted down the door and looked around then screamed in loudly as he can in total anger "SANS!!!!" 

Sans ran from the house and tried to find somewhere to hide.

But some kid spotted him, "Look at this, we found Autism boy!" A fish like boy called out to his friends

"I pretty sure he's mute" snickered one girl monster

"No..." Sans said very softly

"Oh would you look at that, the Autistic kid can talk!" One of them said

Sans got nervous and without thinking about much, Sans quickly teleported away

"What a coward!" The girl monster sneered

Sans will get the last laugh but that's awhile from now

After school walking home with more A+ papers he felt something hit him on the back of his skull

He rubbed his skull then a rock was thrown in his eye socket

"Look! I got him in the eye!" One kid shouted it was different kids, all the kids in the underground hates Sans, they never met him, or  talked to him.

All they see is some mentally ill child who will never be normal.

This is common thing amoug the underground and Sans hates this.

No wonder he spends most of his time in his room with the door locked and the blinds shut.

Sans is a good monster but no one see that, (exept for his family and some adults)

 they say autistic monsters can never love or be empathic, though he has probloms expression concern for others and sometimes is oblivious to their emotions, he is very caring.

But none of the kids sees that in him.

Sans couldn't talk until he was 4 and had problems doing things by himself, and never will be fully independent, but..

It doesn't mean he's not smart..

The children think so.. they all thought he was stupid just because he had issues..

What his mental illness caused did not give him much strife but the greatest strife was what others thought of it.

"Sans? Do you want to play with me?" His brother asked

Sans shook his head and went to his room

 "maybe tommorow?" Papyrus watched Sans shut the door and gave no responce, "oh.."

Papyrus wasn't like Sans

For starters, Papyrus was basicaly everyones friend, and extremely social, and that's basically the biggest difference beside the fact they are two different monsters and of course naturally different
