Sure. I think they could be everything from how we communicate to how we present ourselves so that if we have not thought of what someone's challenge might be, they feel welcome asking for support.
I think when you mention being accessible to wheelchairs and having doors that are able to open, you're probably referring to other very basic physical infrastructure. I think we've all come to understand and know when we see it that it is making an effort toward ensuring we are accessible to those where we can build two standards and fit out two standards that are accepted for meeting people with disabilities that we can recognize.
I think what I'm looking forward to understanding more is really the depth in society, particularly as people age, and as we become more accepting and supportive in general of non-visible disabilities so that we start to understand how we can build our own standards and how we present ourselves so there is a better service standard for accessibility.
