Hmmm, this has got me thinking that i may be dyslexic, i have always suspected that i might be but have never been tested for it.
When i was a child and i first started school i was labelled, well backward for want of a better description, by the education system. They did this pretty much straight away as i recall, like within the first week of starting school. They informed my parents and they pretty much went along with it and they started to say i was a bit thick and would never amount to anything. You know how it is when you are a kid, you believe what adults tell you so i started to believe it myself. Looking back my main problem was that i learned at a fairly slow pace, i could pretty much learn anything but i needed to do it at my own speed and because i was not a quick thinker it was assumed i mut be stupid. I didn't learn to read at school, they couldn't teach me anything. I had trouble reading, writing and with Maths as well. I didn't learn to read at school, it was my brother who taught me to read in bed at night using a comic called the Beano (UK readers will be familar with that one). If it hadn't been for him i would not have learnd to read, or it would have been much later.
Because i had my parents and the school telling me i was stupid i must admit my confidence was very low academically. Children tend to believe what teachers and their parents tell them and i was no different. Because of this i hardly made any effort at school. After i did start to learn to read and write many people pointed out that i had a very unsual style of writing, some words i would write backwards by starting with the last letter and then working to the front. It was just intuitive to me to do it that way, i didn't even notice that i wa doing it unless someone pointed it out to me, apparently i still do it quite a bit but i still don't notice. I used to do that thing you mentioned with the numbers all the time, mixing them up in the wrong order. It's only in recent years that i have thought i was possibly dyslexic.
As i got older i knew that i wasn't stupid like everyone said i was, i just couldn't get on with the education system though. I needed to learn at a different pace and the school just didn't accommodate this. I had also been labelled tupid for many years by now though and that sort of stuck so i was fighting an uphil battle. I hated the way i was labelled. Not surprisingly i left school without any qualifications at all. I never had any confidence when it came to learning. I did eventually go back into education as an adult and ended up going to University after several years of evening college. Even at my University graduation i had to endure a comment about how surprised they were at my achievement due to the fact that i had always been slow. I remember thinking wtf do i have to do to lose that tag. I had thought about having a dyslexia test when i started University but i didn't want to be treated differently so i just worked extra hard to make sure i passed with a good class of degree.
It's good that children don't tend to get labelled quite as much now but i'm sure it must still happen. I'd still be interested to get tested to see if i am dyslexic, i think i probably am.
