For whan sche knoweth al the forme, 560
How that thiself art envious,
Thou schalt noght be so gracious
As thou peraunter scholdest elles.
Ther wol noman drinke of tho welles
Whiche as he wot is puyson inne;
And ofte swich as men beginne
Towardes othre, swich thei finde,
That set hem ofte fer behinde,
Whan that thei wene be before.
