Oh definitely not child abuse - he's 34, which is quite a long way from technical childhood. The only problem with your method is he also (along with lots of other personality traits) has inherited Dad's tendency to argue and fight... and Noddy has taken ninjitsu lessons in the past. I am just glad he never sees me as anything but his little sister because it means I can cuff him up the back of his head when he gets too annoying (like the time he said all slashers were morons).
