cariocas love to be 'cheirosas', which means to smell good,  so perfumes, colognes, and oils might also be a nice idea, but most importantly a good idea is including a card.

cards with beautfiul poems and expressions are heartfelt reminders of the great bonds people share - it might mean more than the actual gift itself, as the words resonate something meaningful. 

april 18th and july 20th are celebrated as 'friends' day'- 'dia dos amigos', which are days to show how special friends and family are in one's life.
