With beach season just around the corner for those of us here in the southern hemisphere, I thought I'd remind you all of the behavior expected of respectable ladies and gents while enjoying a little fun in the sun (never mind that the rules date to the 19th century!). The following excerpt was translated from the Spanish-language book El libro de oro de la argentinidad by Federico Scagliotti.
