@hellomiakoda @Hex There are things that are not exactly normal, like the stereotypical nerd things of being able to understand maths and science. You notice at an early at at school that most people are different.
This kind of difference may lead to taking more interest in these kinds of things, at the expense of interest in the kinds of things that other kids obsess over, potentially leading to a degree of social ostracism.
Being good at something, not a disability but having consequences.
