If you look at Alicia's facebook pics she has some that included her ipad and she was posing.
I was bullied a lot back in school and would be taunted on the bus and then followed home (which was only a block). The younger brother would torment me on the bus and then when we got off, his older brother would pick him up and they'd drive behind/beside me yelling all kinds of names/sexual harrasment type stuff. I was very, very tiny much like Alicia. I had braces, not much of a chest.
Eventually one day I clobbered (sp) the kid upside the head and was suspended. My point being - what if she finally got fed up. I know I did. And this perp was messing with her, tried to take her ipad and then she tried to fight back. She's so tiny he could have hit her once/twice and she'd be down. JMO of course but I cant believe I made it through my h.s. years without causing major damage...that boys head up against the window was NOTHING compared to the harrasment and bullying I received through middle/high school.
Oh and one last thing - they said she'd ask people to play video games and watch nickolodeon. So in that sense, most 16 year olds are not watching Nick....I had no friends and I clearly remember sitting home w/ my little sister (6 years my junior) and watching kids shows. Anything that seems happy and that life might not be all that bad...point of all this - mentally/emotionally she didnt seem 16. There might have been a boy that FINALLY showed interest in her and then something went bad. Maybe thats who she went to see getting off the bus --- another boy? someone older showing her attention?
