Every year around this time, schoolteachers have to fill out their report cards. And school administrations put a lot of pressure on them to put a positive spin on those reports. (Administrators don't want to be bothered with disgruntled parents.)
Here's a guide for all those teachers on how to put a positive spin on various personality types. Like much of life, it's all about euphemism.
ADD, ADHD: Say he is exuberant, energetic, and lively. He has a lot of life force, and manages to stay interested in many things at the same time. He is active, dynamic, spirited, bouncy, ebullient, and tireless.
A bully: Say he is a strong presence in the classroom, forceful, and socially dominant. He has a strong will, and the other children look up to him. He is assertive, and knows what he wants, and strives to get it.
A crybaby: He is sensitive, caring, and very aware of what's going on around him. He is socially perceptive, appreciates others' feelings, and is in tune with his own feelings.
Dumb: He moves along at his own pace, and eventually catches on to everything. He enjoys learning on his own. He is making good progress, and taking some amazing steps forward.
Autistic: He has an original view of the world, and marches to his own drummer. He offers a refreshing change of pace from the run of the mill children. He enjoys his own sense of humor, and has amazing focus when he puts his mind to something.
This should also be a guide for the parents of young children: if you hear any of the above expressions, be aware they may be euphemisms.
