I am sure your brother will help you with making the house warm.

A few weeks ago he went to live in another house with the owner and his family. They have a very warm house. They heat it with fire (wood). He often sleep in the kitchen. He rarely even visit me. I highly doubt that he will help, but I will see what I can do. Maybe other people help (for example the neighbors). Sometimes complete strangers help. I already experienced this multiple times.
