I shall the effect of this good lesson keep
As watchman to my heart. But, good my brother,
Do not, as some ungracious pastors do,
Show me the steep and thorny way to heaven;
Whiles, like a puffed and reckless libertine,
Himself the primrose path of dalliance treads,
And recks not his own rede.

– William Shakespeare

Hamlet, Act 1, Scene 3. This is the scene where we first meet Ophelia. After Laertes warns her not to trust Hamlet’s declarations of love, Ophelia turns her brother’s religious counseling back on himself. Laertes is about to leave for Paris, a city that poses moral dangers for a young man. Ophelia calls on him him not to sermonize like a hypocritial religious minister, to heed his own advice to keep the "thorny way to heaven" and not to tread the "primrose path." She calls out the double standard at work in Laertes’ advice – he warns her to preserve her chastity, so she tells him not to be a "puffed and reckless libertine."
