I can subrscribe to your theory IceLad, and certainly relate to grumblina too
Im 22 going on 23 and I certainly feel like I never acheived in my teens what everyone else did. I don't have an abundance of fantastic teen memories of parties, mates, girls etc. I think Im reasonably mature for my age having spent a lot of time with people a lot older than myself, but at the same time I feel like Im really only 15 or 16 years old.
My teenage years are just a blur to me now and I do wish I could regain them. And yes it can be difficult to see everyone go on with their lives while feeling like Ive been left behind.
Im still looking out for my first proper girlfriend, still looking for a bunch of mates to hang out with while a lot of others my age are spending less time with mates and settling down with long term partners instead. How can I catch up on a decade of relationship experience so I can be on the same playing field as everyone else? I dont know
