Rules are important, they are needed to allow people to live together in a society or at work, but sometimes there is some misunderstanding about them. Some persons love rules, more rules there are more happy they are and they feel very well in respecting them with very high precision.
Persons with ADHD sometimes are maybe supposed to have a problem with rules and authority, so they are convinced to take medicines and follow therapies to become more normal. So, instead of understanding that rules are not always so much necessary, they are forced to add even more rules, to control everything they do.
I suppose that it depends on the level of syntoms that ADHD gives, because if they are heavy oviously there is a need of improved control, because some kind of distracted behavious could even be dangerous.
But if that is not the case, if the behaviour of a person is not dangerous or limitant, why convincing this person that he/she should be more 'normal'? Why giving so much importance to rules when they are not so important? Why do not accept that there could be also a different way of living together in the society, that is not the one that the very precise persons want?
