I was that child. I grew up firmly under the thumb of an over anxious and somewhat obsessive mother. It was awful and I hope the girl in the OP doesn't have the same type of childhood!
I remember she grudgingly let us out onto the road in front of our house as I reasonanly pointed out I couldn't learn to ride a bike even with the special dispensation to be allowed on the drive - before that it was back garden if I was lucky! Them being promised that once I passed my cycling proficiency (at 10/11 yrs old) at school, I could go to the top of our road - a paltry 3 houses on the road, with a pavement, which led onto another deserted residential road in a peaceful and affluent rural village.
Then she took it back and I was banished to the front drive again. I remember the suffocating horror of that chink of freedom being taken away with no reason except a woman's selfish paranoia. The unfairness, the feeling of having been tricked, the sinking realisation that she'd never ever let me be normal. Ugh. The neighbours kids would come and laugh at us, stuck in our cage drive (which was long enough to park a car, no longer, so why the fuck she gave us bikes is beyond me).
They'd hover a meter or two out of bounds, and taunt / tempt us. And my mother would watch silently swelled up with righteous anger just slightly, terrifyingly out of control as she screamed blue murder at me if I dared step that metre into freedom.
And then the other battle, The Copse! Our house was opposite a strip of land speckled with trees, which went behind a row of houses and then backed into a field. This was naturally a children's hang out / play area. Except for us. When I was in secondary school she finally agreed to let me set foot onto the copse... But only 4 meters in! She actually measured it and tolde what tree I was allowed up to. Which was one before the tree where the very small group of children hung out. So I was allowed to WATCH the others play and gossip and run around, and oh the horror when I went that extra few centimetres, and climbed an 'out of bounds' tree. Oh the freedom swinging in the wind sitting high up in the branches. Away from her, away from my life, away from my cage.
What an utter bitch she was. Sorry but she really was, one reason she kept us close was so she could rule her dominion and keep absolute power over us. She assured me that if understand when I grew up etc etc etc, and I do indeed understand. I understand what a nasty, neurotic despot my mother was, and how she deliberately put fake boundaries in place so we were kept apart from being able to make friends, have any relationships beyond the stifling horror of that house.
I have no ide how I'll give DS freedom, as he's only just turned 5, and we live in an inner city area - but I'm going to have to work it out so Im not like my awful mother!
Yes indeed, I am bitter, and I have indulged myself in a rant! :)
