“Don't trust the person who has broken faith once.”

“For trust not him that hath once broken faith”

“There's no trust, No faith, no honesty in men; all perjured, All forsworn, all naught, all dissemblers.”

“Friendship is constant in all other thingsSave in the office and affairs of love.Therefore all hearts in love use their own tongues.Let every eye negotiate for itself,And trust no agent; for beauty is a witchAgainst whose charms faith melteth into blood.”

“For death remembered should be like a mirror,Who tells us life’s but breath, to trust it error.”

“Beauty is but a vain and doubtful good;A shining gloss that vadeth suddenly;A flower that dies when first it 'gins to bud;A brittle that's broken presently;A doubtful good, a gloss, a glass, a flower,Lost, vaded, broken, dead within an hour.And as goods lost are seld or never found,As vaded gloss no rubbing will refresh,As flowers dead lie withered on the ground,As broken glass no cement can redress;So beauty blemished once, for ever lost,In spite of physic, painting, pain and cost.”

“The worm is not to be trusted...”
