In our daily lives we attend primarily to that which the senses are spelling out for us: to what the eyes perceive, to what the fingers touch. Reality to us is thinghood, consisting of substances that occupy space; even God is conceived by most of us as a thing. The result of our thinginess is our blindness to all reality that fails to identify itself as a thing, as a matter of fact.
