Definition: A term used for someone who hides his/her pain and misery behind a fake smile.*

i know you want me to be happy
i know you want the best for me
but it hurts so much
so i hide behind a smile

either you don't know me too well
or you don't care at all
you just don't seem to notice things now
how everything has changed

you used to be my reason for happiness
but if i depended on you always
how would i be happy
when you're gone

now i am truly happier
even if you're gone
you taught me a lesson when you left
because you seem happier without me too
