Isa          Mary! Mary! Can you hear me? I need some help!
Mary      Isa? Where are you? What's happened?
Isa          I'm around here. I was sailing near the rocks and some of them sank.
Mary      Are you OK? Can you come back here?
Isa          No, I think I've injured my arm. I can't move it and it really hurts. What am I going to do?
Mary      Don't panic! Let's phone the coastguard.
Isa          OK, but hurry up! My arm is bleeding!
Mary      OK, OK, hang on! I'm sure that someone will come soon.
Isa          Mary!
Mary      Now what's happening?
Isa          I really need some help, I'm starting to feel dizzy...
