what does it mean to think

what does it mean to think?

is it - fist under chin,
face a little harrowed?
or staring in the distance
eyes slightly narrowed,

maybe a shaking foot,
pouting lips,
furrowed eyebrows
and hands on hips?

mindlessly stirring a coffee,
munching on a snack
moving shoulders to a song
or writing something whack?

i think-
guess i'll never know
what do you think?
