nanook rubs it....
I like the Overground, it usually feels airy. Was it busy or comfortable?I was on London Overground yesterday and almost everyone was wearing a mask (I saw one guy without on the platform at Stratford but he could have put it on when he got on the train).
There were a few noses poking over here and there but not loads and I do feel a bit sorry for people with big noses. It does make them a lot harder to wear. Maybe that's why they were only worn widely in Japan and China before.
