You go to a house with a friend.
You go inside the house and your friend stays outside, but in contact.
You work your way through the house, describing each room to your friend, who listens carefully.
They can’t see anything themselves; you are their eyes. Though they can ask questions, which helps you notice things as you go from room to room.
It’s amazing what can remain unnoticed on trips round houses.
And because they’ve seen houses like this before, your friend can also tell you where some of the light switches are.
They are not always easy to find; and it does help to be able to see.
And if some of the rooms are a mess, or you trip over some rubbish, it can be reassuring to have another saying you don’t need to panic.
And this is therapy.
