Your friend sounds more like a masochist - they're the ones that enjoy pain. It's the sadists that like to inflict it (unless you meant that she's being sadistic in pushing you into doing this again?)
I remember a supposedly sophisticated joke when I was a teenager - a conversation between a sadist and a masochist.
The masochist said, "Hurt me!"
The sadist thought about it for a second and then said, "No."
I do wonder if your friend can take it - it's a bit like easy child, who can ride on the scariest, nastiest roller coaster, but is terrified of flying even in a 747. And for our holidays she booked our transfer flights - she booked a Beechcraft. Nineteen seats. No way can she avoid a window seat - I suspect that if the engines slow down we'll be asked to stick our arms out and flap.
Do let us know how your friend goes. That could be fun!
