How about this:
That girl you said was weird? She has been locked in her home for the past 5 years. That boy you said was dumb? He has ADHD. That boy you said didn't have any friends? He has ASPD. That girl you laughed at for trying to be nice? She's trying the best she can and no one accepts it. The smartest kid in class? Her parents are so strict that if she gets a B+, she gets grounded. Forget what YOU think of people. Everyone thinks im smart? They dont know the decisions I've made that got me nearly expelled. Dont think people are who they are if you dont know them.
