Those very wrongs some people`s lives commit
That make the human race in worth worth naught.
You`re one of them as fas as wrongs permit;
To my good mind you this so clearly taught;
That with advantage you kill with your ills
Being of fair looks the eye don`t see you bad.
But when true show up you evil wills,
The eyes so amazed the hurt makes people mad.
I pretty well escaped deceitful you
And suffered not a heart without repair.
But many have and will the same not do.
For fair found ill does cut till you are bare.
But I will save the ones I can from this
By telling what you are, a poison- kiss.
