This is a new one on me, jb!
I certainly do not recall any type of St. Pat's Day-related assignments being handed out at St. Cecilia School (even though the Irish population was voluminous)...and graded to boot! I don't even remember having to write a composition about St. Patrick. But I can't speak for other schools...
As for this trap assignment - it's only a matter of time before P.E.T.L. (People for the Ethical Treatment of Leprechauns) start rioting in the streets.
In the meantime, I shall salute WNP with a glass of green beer tomorrow!!
