Walking through trees to cool my heat and pain,
I know that David’s with me here again.
All that is simple, happy, strong, he is.
Caressingly I stroke
Rough bark of the friendly oak.
A brook goes bubbling by: the voice is his.
Turf burns with pleasant smoke;
I laugh at chaffinch and at primroses.
All that is simple, happy, strong, he is.
Over the whole wood in a little while
Breaks his slow smile.

Robert Graves
