Ok look you can't judge an entire age group on a load of idiots.
If you go to a school you'll see there are meny different types of people.
Like there is one guy in my year who in pe there is a 80% chance of him going up to some one and saying somthing like your mum was good last night.
theres others who will insult you and you don't care but you should so they insult you more then they try and show off.
This happend to me and my mate up town when 3 kids one had a nose bleed the other had snot coming down his nose the other the size of an ant)Came up to us one called me gay and my mate ginger then they tried to strangle us.
So yeah 13 year olds can be a pain in the arse but there are a few like me and my mates who are ok.
So please consider that there are more than one type of 13 year olds
*at least untill i'm 14 ;-)
