Thin Having relatively little extent from one surface or side to another; not thick. She was always quiet, sat towards the back of class as if she were hiding. She was hiding herself in baggy clothes. She somehow always seemed too out of energy for someone of her age. Always a little too sad for someone so beautiful. A little too quiet for someone so intelligent. Warning: this story contains depressing thoughts or feelings and displays a girl with a eating disorder so if you find any of these triggering, I advice you not to read.
