How did the woman proofread the letter?

W: Good morning, Theodore.
M: Morning. Umm... Do you know how to proofread?
W: Yeah, of course.
M: Er... Can you check these for spelling and grammar?
W: Uh-huh. Just send me over. I love this personal writing to his girlfriend. That is so sweat.
M: Yeah.
W: "Rachel, I miss you so much. It hurts my whole body..."
M: You do not need to read it aloud.
W: OK.
M: I mean, you can if you want.
W: OK. "Rachel, I miss you so much. It hurts my whole body. The world is being unfair to us. The world is on my shitlist. As this couple is making out across from me in the restaurant, I think I’m going to have to go on a mission of revenge..., and I must beat up the world’s face with my bare knuckles making it into a bloody pulpy mess. And I’ll stop on this couple’s teeth for reminding me of your sweet little cute crooked tooth that I love. "I think that might be my favorite one. I made the corrections in red. I altered a couple of the phrases in some of the more impressionistic letters. But I’m not much of a poet, so I think I might’ve messed them up.
M: No, these are great.
W: Really?
M: Thank you.
W: So the real letter, what Roger was saying?
M: I just say that he was in Prague on a business trip. He missed Rachel.
W: So how could you know about her crooked tooth?
M: I’ve been writing her letters since they married years ago. The first letter I ever wrote was for her birthday. And I knew about her crooked little tooth because I saw a photo of them.
W: That’s very sweet. Oh, you have a meeting in 5 minutes.
M: Oh, I forgot, thank you. You’re good.
W: Yes, I am.
