Man, this poor guy.  I remember being picked on like that by my older brother too, although I can't say it was ever as violent as rock-throwing.  You're doing a great job, and I can't wait to see what you have in store for him as a way out of this monotonous nightmare.

I really like the way you've introduced this.  Already I feel for this kid and hope he finds something special. Great writing! I'll eagerly await each chapter. :D

You've really set the scene and the characters in a very short sketch.  I feel sorry for David (having been bullied by older brothers myelf--Lord, that's just exactly the way they act), but I also think he feels a bit too sorry for himself (also the way I did).  It makes me think he's going to get jolted out of his complacent self-pity pretty soon.  His parents are so funny, but a llittle sad too.  I can almost believe his workaholic father would try to work on his laptop while driving.  Can''t wait to read more.
