I was treading water thinking they will come back , but the rope from the tubes had gotten stuck in the prop under the boat . I calmly yelled out please come back and get us . I looked over at them doing there thing over at the boat as they floated father away , I started getting tired and thought ok , they better get back here . As I sat there swimming I thought come on now I yelled come on and get over here .

Question: Why has the narrator been left in the water ?
The narrator 's party do n't realize the narrator is struggling .
