Sexual assault is one thing, but if she was just thrown food at or some such teen age stuff, its time to get over it. Lots of worse things happen but adults learn to get over it. If its that bad, they go to therapy. But Chinny has arrested development and only has memories before age 20 to dwell on. At her age, she should have had more experiences, good or bad, to be thinking about without much emotion over them over time.
