Beware serious, uptight, overly stressed people.
I lurk in the classrooms, school hall, libraries, Wall Street,
Yes even in the churches. My influence will spread.
There will not be a single person who can escape my presence.
I have existed before the dawn of time and will remain when
you are just dust here on Earth.
But, when you arrive in the afterlife I will still find you.
Who am I? I am Laughter.
