Have you ever actually seen her eat anything while she's at school? Even the tiniest thing? I don't say I haven't seen either.
Well, how do you know if she isn't eating at home as well?
And have you seen her shoulders? And her back? And her legs? And her ribs? It's like she's just a Skeleton with a bit of skin on it. It must have taken a while to get like that.
Anything could be happening to her at home, you know? Her parents could be starving her to death, and not feeding her enough.
But maybe, it's her?
