Let your taps drip at eight

I was out last week because
Last was the week that was
What brought the city to its knees
(As happens every time we freeze)

Getting into the swing of things at eight

When the Magi arrived, bearing gifts
Twelfth Night, or Epiphany

But that word can have two meanings
It's also an insight received
A breakthrough or a discovery
The gift for those who believed
