Firstly I'd like to point out that the original series of The Inbetweeners started in 2008 when I was neither a teenager, nor male, however certainly identified with that late-teenage claw through life. Time was when everything was a potential embarassment or fuck-up and you really didn't know whether you were coming or going. Whether it was cringe-worthy encounters with the opposite sex, the endless quest for "cool" or the feeling of being slightly out of place in every possible situation.
I also identified greatly with the sentiment of the "Inbetweener", halfway between childhood and adulthood and not really sure if you want to be either. The thing is now in my *cough late twenties, I would have assumed that my "Inbetweener" stage was over and I'd be well into my adjusted adult phase where everyday life was a breeze and my problems were only important, real things like death and taxes.
I have since discovered that is not the case.
