Famous quotes containing the words families, venomous and/or snakes:
“For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.”
—Sara Lawrence Lightfoot (20th century)
“Nor envy’s snaky eye, finds harbour here,
Nor flatterers’ venomous insinuations,
Nor cunning humorists’ puddled opinions,
Nor courteous ruin of proffered usury,
Nor time prattled away, cradle of ignorance,
Nor causeless duty, nor comber of arrogance,
Nor trifling title of vanity dazzleth us,
Nor golden manacles stand for a paradise;”
—Sir Philip Sidney (1554–1586)
“Granddaddy used to handle snakes in church. Granny drank strychnine. I guess you could say I had a leg up, genetically speaking.”
—Wesley Strick, U.S. screenwriter, and Martin Scorsese. Max Cady (Robert DeNiro)
