When I was in school, the fat kid or kids were usually the few who were socially awkward/different in some way, low economic status, a few were the mentally retarded/autistic, maybe one came from a family who were all very very over weight, and may have been excused for by the not yet well researched runs-in-the-family argument and so on.  My point is, they stood out.  I could count them on one hand and for almost every one of them, obesity was usually not their only problem in life.  Allow me to tell you (as if you don't already know) who the fat kids are today.  They are.........the  cheerleaders, the football team, the mentally handicapped, the nerds, the Mexicans, the whites, the Asians, the potheads, most of the sports teams, the members of the drama, chess, math clubs, you get the idea. They do not stand out anymore.  Their skinny friends stand out, and their skinny friends are quickly disappearing.  High school has become less about fitting in and more about fitting in to the ever more 'relaxed' sized jeans from the mall. What may still stand out is the morbidly, very morbidly obese.  "At least I'll never get that big," thinks the overweight 9th grader as he washes his french fry lunch down with his/her third coke of the day.
Schools are forced now to supply classrooms with tables, as more and more of them can not fit into the desks.  They don't have to pay extra money to attend school but as any airline knows, were already paying the price.  Even in this very desensitized world we live in, I am still disturbed by the fact that this problem is only getting worse every day, are you? Sorry for the poor grammar.
