I was potty trained by 2/3, but kept having rare accidents at school until 14-15. This was basically because I was too shy to ask to go to the toilet. I did, and still do (when not in little space) hold off, and end up doing the loo loo dance. In fact, the only reason I realised I still do it is because my mum told me a couple of times recently!
