“1928, Martín Adán (Rafael de la Fuente Benavides), La casa de cartón. El pregón de una lechera cayó, inesperado, en medio del cuarto y, al cabo de un minuto, las seis campanadas de las seis de la mañana.” — (please add an English translation of this quotation)
*From Latin lactārius, corresponding to leche + -era. *(police van): Because the first vans used by the Spanish police in the 1970s were also identical models to those used for delivering milk. Another reason is that the riot police officers came out of the vans distributing leches (“bumps, blows, smacks”).
