'That was the she ever saw them'

Every year my friends Carol, Mark, John, Lean and me go to 'The extreme camp' where we practise every kind of extreme sports.
Las year I couldn´t go because my mother was very ill, so they went without me.
Every year there are a lot of new campers, last year there were only three, Mathiew, Jake and Gallery. They were best friends but that year they quarrelled a lot so their parents decided to send them to the camp to see if they could get on well again.
On the second day of the camps activities started. There were three groups and the trhee ex-friends were together with my four friends.
This group went to the mountains, they did mountain biking, mountain boarding, outdoor climbing and rapel, but although the seven teenagers took it very well, the three new hardly spoke to each other, there was no sign of friendship.
The days passed quickly and when they realized, there were only three days missing.
It was monday, it was the last activity and they went to the beach. The plan was to surf and windsurf, but first they were going to visit a small island.
When the teacher arrived, Carol and Gallery, Mathiew, Mark and John and Lean and Jake were talking separately, the three friends didn´t even talk to each other. But Tomas, the teacher, separated them into two groups. John, Mark, Lean and Carol were together. Gallery, Jake and Mathiew complained but it was nmo case, there wasn´t any change.
Tom went with m,y friends in a boat and the others were alone in the other.
Tom was explaining, but group 2, the ex-friends, were arguing all the time so they didn´t hear anything.
When they were in the boat, group 2 didn´t know how to turn round so they went to the other side.
Tom was desesperate, he followed them but it was late. They were out of control, Tom stopped to tell the driver of the bus to take group one to the camp and then again to take him a the others, and so he did it, but about three o´clock, the driver returned alone, he had waited nearly five hours but no one had returned.
When Carol told me that, she started crying and said that that was the last time she ever saw them.
