if you look at her closley
you can see that,
ever now and then
she turns away from her group of friends
her smile falters
and she becomes another person for a few seconds;
a sad person
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 fake smile.
