Empty Faces
stare back at the desk
they sit in
those are the tired ones

Faces Full
of happiness
laughing at a joke
their friend just told
those are the happy ones

Faces of Concentration
trying to reach their perfection
by completing their homework,
Homework
no one else seems to be doing
those are the determined ones

Everyone
every few seconds
glance at the clock
hoping the class will be over
but to them
it won't come soon enough

uder pressure
