I am reading Out of my Mind by Sharon Draper.
I have questions about the last sentence in Chapter 11.
(For your information, Rose is a normal kid and "I" am a physically challenged kid. They became friends after "I" joined the inclusion class)
Rose tells me secrets sometimes. I know she bites her fingernails, and she hates milk. She goes to church every Sunday but falls asleep until it's over. Me too. She has a younger sister just like I do. She even likes country music. Sometimes she tells me about trips to the mall with her friends.
It would be so tight to be able to do that.
I was wondering what that in the last sentence refers to (trips to the mall) or talking about the trips to the mall?) or what the whole sentence means.
