Two quotes I saw recently used for popular purposes, taken completely out of context:
1. On a mug for sale in the Barnes & Noble cafe: 'I have measured out my life in coffee spoons.'
No: this is not a cute little quote about how much we love coffee. It's from 'The Love Song of J. Alfred Prufrock', the subject of which epitome of a useless, wasted, ineffectual, small, little life. Is that how you want to 'measure' yourself?
2. Positive Valentine's Day quote: 'You must allow me to tell you how ardently I admire and love you.'
Yes, it's from the 'dreamy' Mr Darcy in proposing marriage to Elizabeth (we're talking Pride and Prejudice here). But it's his first proposal, when he is intolerably proud (albeit, she is completely prejudiced). Doesn't the quote conjure the whole scene for you and make it unacceptable as a V-Day sentiment?
Flame off ;-)
