"don't cry because it's over
laugh/smile because it happened"

this is a very convoluted statement
it contains many aspects that i personally don't like
the first being that
the manifestation of an emotion
is very black and white
in society
crying is often associated with sadness
laughter and smiling with happiness
but that's not always the case
someone who is mourning can smile
someone who is suicidal can laugh all the time
someone who is happy can cry or remain silent
the point is
an expression of an emotion varies greatly
it depends on the individual

the second being that
it interrupts the process of grieving a symbolic death
one of its underlying messages is
stop engaging with the emotions that come with the end of this particular season
in this case
it is whatever "happened"
it tells people to just smile/laugh
now i understand that it may be therapeutic
in some cases
to change perspective at times
however
do not encourage this all the time
sometimes
a person just needs to sadly cry over something
and not be interrupted
remember
the body understands itself
more than our perception of it does
allow the body
to release the emotions stored within
don't hinder it with your mind
that has been trained by society
to shut down and abandon or shame those emotions
