" Amy always tried to maintain some semblance of dignity in front of me. Even so, I never met the same Amy more than once. On some days she behaved like a small child, sucking her thumb, talking in a baby voice and sitting on my knee; at other times she'd adopt the aggressive, butch act, the Rizzo character - the girl who had 'out-Jaggered Jagger'. The more vulnerable she felt, the more pronounced that persona would become. I think she brought her characters out as coping mechanisms, to get her through anxious moments or stressful situations.
In all honesty there was rarely a time at Camden Square when Amy was a whole person. Rather, she continued to be this fragmented girl, a series of creations I suppose I'd become accustomed to. "
