"He's been dragging equipment down the stairs at all hours of the day and night, sweat running in rivulets from his hairline."
-This is a metaphor because sweat isn't actually running down like actually rivulets. The author is just comparing using figurative language.
"The whole world seems contained in the square blanket we're sitting on."
-I would consider this personification because the world can't really be contained on the blanket the girls are sitting on.
"In my head I talk to Faye as if she were here, but she's not-and besides, it's always hard for me to explain my churning feelings."
-This is a metaphor because she is talking about her feelings churning. Her feelings can't really churn inside her body, therefore it is a metaphor.
