Blankets to stay warm on the streets, and eating raw onions to stay warm inside the body. One of them takes the bus to stay warm and likes to sit upstairs on the bus and feel like a tourist in London. He puts on his hat, which is for warmth but also for style and to feel more like a tourist on a bus.
The ground is very cold itself, so it is difficult to ever be warm. Tired of having hot coffee all the time, which people keep offering to buy, but it is horrible to have that much caffeine in the body.
