The New York Nexus Cafe 

Beware of things in duplicate:
a set of knives, the cufflinks in a drawer,
the dice, the pair of Queens, the eyes
of someone sitting next to you.
Attend that empty minute in the evening
when looking at the clock, you see
its hands are fixed on the same hour
you noticed at your morning coffee.
These are moments to beware
when there is nothing so familiar
or so close that it cannot betray you:
a twin, an extra key, an echo,
your own reflection in the glass.

I like this one :) thanks.

I swear I saw this on the "Poetry in Motion" series on the NYC subway...

cha-ching!

[I bought some poetry in motion posters from the transit museum in Grand Central Station a little while ago and The Gift and Beware of Things in Duplicate were two of them]
