Growing up, I was conscience of adults disapproval, not at me as a person, of course, just at me as a body. I was solid, weighty, immovable, I could not be easily lifted, nor could I be easily pushed on the swings. I defied their idea that children should be small, as I had as much matter as an adult. My needs were those of an adults, for the pain of my condition gave me an early appreciation of adult knowledge, that people are inherently cruel. I was ostracized, fat kids always are.
Children are quick to hate what's different, unusual.
Obesity in a child is unusual, it reflects back on the parent. It bespeaks gluttony, chips, popcorn. My mother worked. My babysitters, cousins, aunts, often preferred bribing me with sweets into good behavior. A fat child is always faced with mute words, get small.
