On some blue mountain Monday, you will leave me
Like one leaves a cabin, or a dog-
No woods enchant much longer than a weekend;
And pets are work, like cutting winter logs.
A fence you never mended goes forgotten,
A barn you never painted's left behind-
Invisible, as soon as past the parting;
As conscienceless, as dreaming is to mind.
