  • The heat of the day can be cruel.
    We swelter and yearn to be cool,
    To sip a cold drink
    And watch the sun sink
    And soak in the sweet crepuscule.

  • This word has the dubious distinction of being used in Scientology matériel like so:

    "Here is an example: 'It was found that when the crepuscule arrived the children were quieter and when it was not present, they were much livelier.' What happens is you think you do not understand the whole idea, but the inability to understand comes entirely from the one word you could not define, crepuscule, which means twilight or darkness."

    There you have it, from L. Ron Hubbard himself.
