I had been taught to read and write before I started school, I remember reading to Mum from the newspaper and will never forget the word 'municipal' because of it!They actually did that to me, my father went up to the school to complain, but it made no difference. That happened early, before I got to the writing stage and it delayed my learning from there on, quite a bit. I think I maybe became 'reluctant', as a result of the treatment, whereas I had begun school a little advanced of the rest.
Of course I had learnt the alphabet as 'Ae, Bee, See' but at school got totally confused with the pronounciation method and remembering telling Mum she was wrong.
One of the things we learnt at school was 'You write with your right and what's left is your left' try learning that parrot fashion and trying to get left and right wrong. it wasn't until I was 9 and got run over by a car, breaking my right leg and creating ongoing problems with my left that i found a way to work it out, to this day any confusion is always referred to 'it's my left leg that hurts'.I didn't know that.
I think the only problem I have from the switch, apart from the hand writing, is a slight confusion between which is left and right. I tend to look around when picking up knives and forks, to remind me which hand each belongs in. Usefully, I was always able to work and use tools with either hand.
Equally I find I'm fairly ambidextrous as so many tools are designed for the right hand. But I never did learn to cut straight.
