I used to have my meals at a vegetarian restaurant. Here I met Mr Albert West. We used to meet in this restaurant every evening and go out walking after dinner.

My co-workers and I had reduced our diet since the outbreak, as I had long made it a rule to go on a light diet during epidemics. In these days, I had therefore given up my evening dinner. Lunch also I would finish before the other guests arrived.
I knew the proprietor of the restaurant very well and I had informed him that, as I was engaged in nursing the plague patients, I wanted to avoid the contact of friends as much as possible. Not finding me in the restaurant for a day or two, Mr West knocked at my door early one morning just as I was getting ready to go out for a walk.
