Fair weather supporter

“Don’t hear much ‘bout Shels these days,”
My workmate loudly jeered.
“Have they vanished in the haze?
Gone ‘pop’ and disappeared?
While they enjoyed their huge success
You bored us all to tears
With tales of Shelbourne to excess,
For years and years and years.
But now their star is on the wane
And down a league or two,
We do not hear this Shels refrain
Ad nauseum from you.
You say you are a Shelbourne man,
And that’s the way it goes?
But has this sad fair-weather fan
Gone off to follow Bohs?”

“Oh no,” I smiled. “I don’t say much
And here’s the simple reason.
There’s nothing much to say, as such –
We’re still in the close season.”
