As a teenager .. I can only say my poor mother, lol.
I was loud and a class clown in some subjects at school but in others i was quiet and a nerd. I enjoyed my art classes where i was free to be creative. I never gave a shit about being with the 'in' crowd and i didn't wear all the latest fashion labels. I was a rebel. I was protective of my friends and probably more masculine back than than now. I was really surprised at 14 when i completed my SATS (mock exams) and came 4th (out of 200+ kids) in English as i never paid attention in that class (Teacher had bad body odour issues). I always lived in the moment and didn't worry about the future. I had a lot of laughs.
I learned a lot during my teenage years, both good and bad, for which i am grateful for.
