It would be 15 to 16 for me, I always hung out with older guys (looking older myself) and as they were getting into new places I was coming too. Got my leg over for the first time on my 15th birthday. Drove a Jag to school when I was 15. Started using the term "chief" and felt like I was cool. Got on with everybody really well. Had a stunner for a GF. Played a set with Dodgy at a charity do too. Had some really good mates, and was at weekly boarding school. The sort of shit we used to get up to and away with was great, and we used to rip the piss out of anyone and everything. I had my first proper fight at school when I was 15 and everyone stopped picking on me after that, and then everything was easy. Good times, good times. Just wish I could go back and try a bit harder. And wish I had of stayed on at School till the end....
