We have our local homeless (by choice) person, Brian. Every winter I fear will be his last but he seems to survive. He was offered accommodation in the next village which he accepted - for a week - and then moved out. He just doesn't do indoors. He has a tent in the summer in the woods and in the winter dosses down in the shelter in the village cemetery. Everyone looks out for him and gives him warm clothes/duvets/boots and hot food. He used to have a good job in Dunn's the gentleman's outfitters in London, but one day just walked out and never went back and fetched up here, in Fife, about 12 years ago. I think he's comfortable with his lifestyle and the local support he receives.
I wish you luck GA in sourcing your emergency accommodation.
