The Lily

Been thinking that my memory must be clogged with tech blurb from the books, blogs, and programming languages I deal with daily. As a way to kind of balance that (yeah, in my head this makes sense), I will try to memorize something non-techie every now and then.
This week's candidate is a short poem by William Blake (I'm aiming low to begin with)

The modest rose puts forth a thorn
The humble sheep a threatening horn
While the lily white shall in love delight
Nor a thorn, nor a threat, stain her beauty bright
