Why to learn how to speak other languages

"Then said they unto him, Say now Shibboleth:
and he said Sibboleth: for he could not frame to pronounce it right.
Then they took him, and slew him."

– Judges 12:6

In Brazil:

• Pulling at one's earlobe is a sign of appreciation.
• Flicking the fingertips underneath the chin indicates that you don't know or understand the answer to a question.
• To beckon someone, extend your palm face down and wave your fingers toward your body.
• The "O.K." sign [using your first finger and thumb to form a circle] is considered vulgar.
• Machismo in Brazil takes a milder, more subtle form than in other Latin American countries. Moreover, it's important for men to appear self-assured and "in control" at all times.
