I don't honestly think I am jealous of young girls. I think my life would have been a whole lot harder if I'd been born a girl.
In some ways, as strange as this may sound, being born male was perhaps beneficial to my early upbringing.
I'll try to explain:
When I was growing up, we had very little. After my dad met someone else and split, mum was left to bring up three boys on her own. And he paid absolutely nothing towards it at all. He practically disowned the four of us.
Since I had two brothers, they kinda got my clothes when I grew out of them, and it was easier to buy all boy stuff on the premise that it would be interchangeable between the three of us than it would have been to buy seperate stuff for two boys and a girl, especially since finances were strictly limited.
So... I think that, in a lot of ways, if I'd been born female then my life would probably have been a lot tougher than it was, although it wasn't exactly a bed of roses anyway. But being envious of a life I should have had is, in my case, too selfish a thing to indulge in when that's placed in the bigger picture and how it would have impacted on everyone around me. And it very likely may even have been a life that I wouldn't have been able to fully appreciate and make the most of.
Besides which, everything that I was has played its part in making me who I am now, good or ill, and to yearn for something which would have radically altered my current state of mind... I wouldn't be me. What's happened has happened, nothing I can do about that. What I can do is make the most of who I am and what I have. Which is really all any of us can do.
