You don’t know what sadness is
until you’re the only one throughout your friends who’s tired of hearing the same joke and don’t laugh at all
You don’t know what sadness is
if the only thing you could ever really care about is passing that one exam when you should be enjoying dinner with your family
You don’t know what sadness is
when you see other people with big smiles on their faces and question are they really enjoying life
  or are they deceiving themselves

You never knew that you’d end up being sad
over that one person who boarded the plane at 3AM and realizing that only after a few hours after they’ve gone, you needed them
You never knew that you’d end up being sad
over that one person who manipulated you into false happiness
You never knew that you’d end up being sad
over that one kid you never knew and the only time you did know was when it was the morning of his death

You see, you are so sad that you never realized that you are currently experiencing the worst sadness

You didn’t realize that you’ve cried so much
to the point where the only thing you did
was sit, and sit, and sit,
through all the weeks, through all the months
that you never noticed you’ve been feeling sad for the past three years
