Uhhh wha?
Maybe it's just me, but I tend to enjoy a hint of reality.
Firstly, I wouldn't take some randomer in off the street and let them live with me. o.o and my parents wouldn't let them either. And I've never heard of someone being killed by being whacked over the head with a lamp. At most I guess you'd get a nice bruise.

Well, I'm sorry you feel that way. I spent time following where I felt the story needed to go. And it wasn't as if he MEANT to have him come stay with them for more than a few minutes. He was doing a good thing and helping out someone who was in trouble, which is what you do when you live in a small town like mine. And it was a marble lamp. Trauma to the head. It can happen. :)
