I did write one on Jennifer Crow's blog (I am using "the brightest" not "effulgent"), but my kids aren't crazy about it because I wrote "we sing like angels" and they don't particularly think we do.
(I don't know why - I mean, how many families can sing SATB music? Kirk sings bass, Sean sings tenor, Yvette sings alto, and I sing soprano and we do a good job on "The Carol of the Bells" but I digress...)
Sean suggested I use one of last year's poems, which I might just do in order to get these cards out. Last year, I had the opposite problem -- I wrote too many Christmas poems and couldn't decide which one to use. I don't know why exactly, but I'd prefer to write a fresh one...just stubborn, I guess.
Or, it takes away the excuse for procrastinating....
