Mel is talking about her ex-boyfriend who hurt her by saying he doesn't like the girl who can talk to ghosts. What is "first cut and all that"? Is it "she got the first cut(hurt) and that's everything? No more than that happened since the first hurting?"
g.w
Mel- Never called me, never came to see me again after a year.
Jim- Still hurts? I guess.
Mel- A little. First cut and all that. And now he wants a second chance.
