I decided to try to do my big shop at the same time as Ms S's little shop, so drove to the supermarket.

It was a little confusing keeping everything separate, so I ended up getting in some extra steps by doing two laps of the supermarket. First pick up Ms S's list, then my own.

After loading up the boot of the car, I walked Ms S's shopping to her house, via a second shop to pick up the last few things on her list.
