There are many things that we would throw away if we were not afraid that others might pick them up. - Oscar Wilde

Cecil Graham: What is a cynic?
Lord Darlington: A man who knows the price of everything, and the value of nothing.
Cecil Graham: And a sentimentalist, my dear Darlington, is a man who sees an absurd value in everything and doesn’t know the market price of any single thing.

Pray don't talk to me about the weather, Mr. Worthing. Whenever people talk to me about the weather, I always feel quite certain that they mean something else. And that makes me quite nervous.

For a sentimentalist is simply one who desires to have the luxury of an emotion without paying for it.
