There were 4 people, S uses a walker.
S was watching J who is blind learn how to navigate the rute to my house. The 2 other people were describing different things to us, One of the tactile landmarks was a metal great. They was saying when to turne left or right, they was telling J to avoid the speed bump.
They was telling J: where to go, how to get there. S enjoyed learning what this experience is like.
