Kruger, you're so hard!

Yes, literally, Kruger is my life helper from daytime to nighttime.

It is getting colder and colder in the bush now, I feel like the temperature has turned down below zero at night. My little hut can not prevent me from freezing at this moment even though it did isolate me and the cold wind. 

Lying in the bed and wrapping myself tightly into the sleeping bag, I also put two more layers of the fur blankets on myself. However, it still feels like I am sleeping inside an icebox, and I just can't stop trembling.

The wind is howling outside the hut, I can even hear it swishing across my roof. The air I exhaled immediately became white vapour and disappeared in the air. If I was not cold, I would like to play a game called "I pretend to smoke", but this time, I was too bitter to enjoy this little fun. 

What should I do now?
