At 31 I moved from Italy to London, UK. I used to believe that the phrase "out of spit" was a particularly graphic and rather dramatic way of expressing one's animosity and vengeful intententions. Only 8 years later, after moving back to Italy, I eventually realized that one is supposed to say "out of spite".
