To be honest I can't remember but I'm sure if I asked her she would. Dyslexia has it's funny moments but if can also be quite distressing when assumptions are made around work ethic or intelligence but all three of them get on with it and it hasn't really held them back.
Just double checked the one my boss used its called Dragon naturally speaking, I told a friend about it and the massive change in their messages was amazing.
You can honestly tell the difference between someone with dyslexia and just being plain lazy I have found.. you can tell if someone is intelligent regardless of errors in typing.
With my fibro fog sometimes I write words that do not even have anything to do with the subject matter, I have to laugh it off and apologise when I realise it!
