If you look at her closely
You can see that
every now and then
she turns away from her group of friends
her smile falters
and she become another person for a few seconds
A person who is broken and damaged
and after a few depressing seconds
she goes back to the group
smiling and joking around
she almost looks like, she is actually happy
but if you look at her closely
you can see how spurious her smile really is
and you can see all the wreckage behind her perfect' fake smile.
