everyone greets with a kiss. However, it is more of an air-kiss/cheek-bounce than a real smacker. Word of warning, paulistanos kiss-greet only on the right side, but cariocas do their greeting with two kisses, one on each cheek. This was difficult for me to get in the beginning, because most of my kiss greeting experience had been in Rio de Janeiro. So I’d automatically go for that second kiss, causing the paulistano to pull back in surprise. Awkward. Eventually I learned to pause after the first kiss and let the other person initiate the second if necessary, because you often don’t get a chance to inquire about a person’s birthplace before they go for the beijo. Be warned, the Brazilian might also grab your shoulder to get in at a good angle.
