"when it is a matter of two socks..."

I just finished knitting some more socks--very satisfying! It feels warm while you're making them, then you pull them on, and you're instantly warm and cozy.  Neruda got it exactly right in "Ode to My Socks"

beauty is twice
and what is good is doubly
when it is a matter of two socks
made of wool
in winter.
