Why was she thinking this?

Why is she thinking this?
Let me tell you a story.

When we were in 4th grade
We talked about our crushes on boys
Who we liked, who we thought was cute?
Who we didn’t like and why?
In 7h grade we talked about
Rumors and experiments
In 9th grade we talked about
You moving to a different school
And missing you
Now in 11th grade
We are talking about keeping you alive
Why are you thinking about this?
Why can’t we live in the 4th grade forever.
