This makes sense--her mother has been through a real war and Amelia hasn't--plus, she's young enough to believe that nothing bad is going to happen to _her_. As a mother, I know that one really well!

"Her mother was supposed to support her every decision" - Does this count for all parents, even muggle ones, or just Amelia's? If it counts for all parents, then mine never, ever got THAT memo!
"I don’t want to loose you." - That should be: ' I don’t want to lose you.'
