See a different point of view...

You are in middle school, and you are walking into a classroom. You are one of the people who are very quick to notice the small things in the classroom. "wow...Jimmy is such a slacker! He is doing his homework in HOMEROOM...", you think to yourself.
"Wow, Annie is so heavy, does she ever even THINK about eating healthy?"
"Joshua is acting so slow sometimes, someone should put him in special ed."
You see, Jimmy stayed up all night trying to cheer up his little sister after she was having nightmares that wouldn't let her sleep for HOURS...
Annie is heavy because she just recovered from cancer, and the Therapy makes you gain weight.
Joshua isn't "slow", he is dyslexic which means he has a hard time with math and writing and reading....
