if everything happens that can't be done
How we cite our quotes:
(and birds sing sweeter
tell how) (20-22)
Again, these lines seem to point out a negative about books that we've never really considered before – that books don't sing. Birds, however, do, so perhaps we should listen to them rather than what we read in a book.
(with a shout
around we go all) (33-35)
These lines bring us back to the glee and joy of recess. They make us think of a circle of kids, spinning around and shouting some word game. Ah, remember the good old days of elementary school?
(we're everything greater
might mean) (38-40)
These lines are the finale of this poem's anti-book sentiments. "We" – which here means the couple in this poem, but probably also people in general, and specifically people who are in love – are just plain better than books.
