What does this mean:

"It's as if I can see the thoughts running in and out of my head like Metro Center at rush hour."

What even is that??? Metro Center is a subway station in DC. Wouldn't it be better to compare it to a busy subway train? But is that what's going in or out or is it the people going in and out? Someone explain that to me, please.

That's not why I hated the book. I hate the lead and I hated the story. I could not relate to her or anything in her life. What ever happened with her mom??

I am surprised at the lack of isolation for someone who needs to stay healthy. Parties. Restaurants. Visitors in the hospital with no protection.... Also! Her reaction to finding out he was sick was the worst! Like, how selfish can you be? The dude is about to pass out and has a nurse and an IV and you somehow make it all about you. Be an adult. Leave when he asked you to and go home and work it out, but don't kick a sick man when he's down!
