I'm not qualified to diagnose her, but I have a lot of experience and knowledge about autism. This girl shows many traits of autism. The lack of eye contact when speaking to someone and being spoken to, the exaggerated facial expressions, especially in situations where the facial expressions are not suitable to the situation, her lack of social and communication skills, the nose picking/eating, screaming inappropriately etc. She also seems to struggle with social cues. She seems to be in her own little world a lot of the time. I am glad she's gone as she was a bit unbearable with the screaming and the selfishness, but I do think Lily is a nice person. She is just very eccentric and very much like marmite!
