hard to say what I would do. Well, I overreact so I would freak out and think "of course the ship is sinking!" (history of bad luck) and get something warm to wear and get on a boat. But I'd try to get some of the 3rd class kids on too. Or if I had the time, I'd work on making rafts out of tables and life-jackets (yeah, maybe it would look dramatic to all the people who were convinced the titanic wasn't sinking but oh well). Sounds like something you'd hear in a worst case senario handbook.
1) I'm a girl so it wouldn't be as bad as if a guy got on
2) But I'd still be guilty about others not being able to get on (me being saved instead of some else)
3) so I'd be the kid in the boat with the 3 five year olds in my lap with my coat wrapped around all of us saying "Go back and get them!!!" (the people swimming off).
