Empathy is what separates us from the rest of the animal kingdom. We have an ability to imagine things the way that others see them and how it makes them feel. We don’t even have to have a disability ourselves. Accessibility is NOT a checklist. Accessibility is about usability. Accessibility is a paradigm shift. Accessibility is a personal issue.
