Mass is not proportional to volume,

a girl as small as a violet
a girl moves like a flower petal
is pulling me towards her with more force than her mass
just then i am
like Newton's apple,
i rolled towards her without stopping
until i fell on her
with a thump, with a thump thump

my heart
keeps bouncing between the sky and the ground
it was my first love
