You will find the answer to that all over the internet, I’m sure. So, I’ll let this little haiku suffice.
Haiku in a Haiku
Three short lines do catch
the form language and content of
five seven five beauty.
Thus begins my foray into writing in the haiku form.
A sparkle in his eye,
Wedged into her smile and
Tore it forever.
He beckons you to come see
The doors bang in hollow nights and
His silent vigil.
