Who is visible and who is invisible?
Is it the beggar sitting on the ground asking for charity, or the running woman who will not be there within a blink of an eye?
In many ways, they both are invisible. We tend to see beggars as people who take advantage of the kindness of others. We think they can work and contribute to society just like everyone else.
Therefore, when we get to see one, we mostly avoid eye contact, as if they were invisible.
The running woman was visible for a few seconds, and then disappeared on the wind.
