well I know more about raising a kid than mostpeople my age that know how to use a condom, no its not my son, its my nephew, his father is a useless sack of scum and because of that my sister had to leave him to my mother and me while she completed her studies. He is 9 years old, I am 20, I started to take care of him when he was only 4, and I am not the best tutor in the world, I mean I raised him mostly when I was a teenager, and it was my mother the one that actually paid for his every needs, but I thin kI did a good job given the circumstances, he is a shy boy, but I thin kthat is mostly genetic, but he is not a bullly as far as I can tell (he was in the same school as I was) he can be a pain in the ass with some tantrums but thats part of the course with kids younger than 10, I didn't punish him phisicaly that often, but If hadn't hit him when he was being a little jerk he woudl have ended up as his father, rambke ramble.
I also have experience with bullying, with being bullied, and schools are half about stuies and half about socially surviving, bullies only bully people they know wont fight back, whe nI was 14 I stopped most of the bullying directed at me by kicking the "leader" bully in his back (he was that short compared to me) they resroted to childish insults the following years but by then I had already stopped giving a fuck about most of my classmates.
