How Long Is a Fad, Just a Fad

A fad is over,
Before I know of it.
By the time I hear
That something’s a thing,
It’s already done.
New dances, new fashions, new food,
New art, new wine, new beer,
Each has a moment
That slips past my ken,
And then,
It’s gone…
Quick as a wink…
Like yesterday’s news,
Except to be fair,
Pink hair,
Which I saw and said…
It’ll last a season,
But never two.
And still it’s here.
Why?
I asked then,
But now, why not?
And rap, is surely a fad no more,
But a graybeard genre,
That, heaven forbid,
I’m getting to like.
