It’s a informative phrase about the bus arriving
First off this is an AMAZING book! It is so beautifully written. But to answer you’re question
1) “I fought my way to the coffee cauldron like a wild beast”
2) “On my return from the bread distribution, I found my father crying like a child”
3) “The cry of a wounded animal”
4) “The soup tasted like corpses”
I hope this helps!!
