Laughter is simply a smile heard out loud, that echoes happiness and love - The Coach

Laughter dies out but is never dead
Laughter lies out the back of its head
Laughter laughs at what is never said
It trills and squeals and swills in your head
It trills and squeals in the heads of the dead
And so all the lies remain laughingly spread
Sucked in by the laughter of the severed head
Sucked in by the mouths of the laughing dead

Harold Pinter

Laughter is a melody, a concert from the heart
A tickling by the angels, creative living art.
Laughter heals and comforts, it’s sometimes gentle, sometimes bold
Laughter is a freeing dance, performed within the soul - Anonymous
