...for a plastic bag for dog poo? I only realised I didn't have a dog poo bag when the dog had done a poo (I'm not the poo troll)! So I went to knock at the nearest house to ask for a plastic bag. The first 2 houses didn't answer, the third house looked like someone was in (fire going) but it had a sign about no callers, so I didn't know whether I could knock or not. As I was wondering, another dog walker passed so I called out and luckily he had a spare bag. Hopefully this will be enough to make sure I never forget again, but if I did, would you knock for a poo bag or not?
