(Iain and Sarah are on their way to an appointment.)

Panel 1

(Iain is leading Sarah through a park. There is a bench behind them.)

Sarah: Iain, wait. Can we stop a minute and sit down?

Panel 2

(Sarah pulls on Iain's arm.)

Iain: Sorry. There's a bench back here. Guess I didn't think about your stamina.

Sarah: Oh, I've got stamina. But this is harder that you think.

Panel 3

(Sarah and Iain sit on the bench. You can see a bush behind the bench on the right.)

Sarah: I'm not just walking, right. I'm feeling my way, every step. It's the stress of uncertainty that tires me out.

Iain: Even with me looking out for you?

Panel 4

(Side view from Sarah's side of the bench. There's a house at the top of a slope, with trees around it and someone pushing a pram nearby. Sarah holds both hands out to emphasise her point.)

Sarah: You can't replace real eyes, Iain. I'm getting used to the cane but it's not quite perfect either. People assume I'm either a complete invalid or an extraordinary expert.

Panel 5

(Front view of them both again.)

Sarah: The truth is somewhere in between. I'm learning. I'm coping, mostly. If I take things slowly, I'll be all right. Even walking - for now - but I'll improve.

Iain: I think you do all right, Sarah. It's me who needs practice.

Panel 6

(They start to stand up.)

Sarah: Nah, you're fine. I'm ready now. Let's go.

Panel 7

(Iain and Sarah start to walk away.)

Sarah: We can speed up. Not an invalid, remember?

Iain: Good. We're terribly late.
