Sarah's house provided a convenient location for an interview with Sarah due to her disability. It gave the scene a warm, homely feeling and showed the bond between Sarah and her hearing dog. Milly's garden was originally chosen for its relaxed atmosphere and pretty surroundings, but poor weather required relocating to a classroom. The classroom offered peace and quiet for good sound quality, space for the dog to run, and had been pre-approved as a backup location due to contingency planning for bad weather.
