Pick up the nearest book to you.
Turn to page 45.
The first sentence describes your sex life in 2012.

Page 45 is just a table. The first sentence on page 46 is "Comme la plupart des mots terminés par une voyelle, les mots féminins ont des formes de pluriel sans adjonction de suffixe, par simple modification de la finale." Which translates, roughly, as Like most words ending in a vowel, feminine words form plurals without adding suffixes, by simple modification of the final [vowel].

Mysterious.
