Friends are not viewed in compartmentalized factions in rio de janeiro, rather, they are part of an ever-expanding circle - for this reason, cariocas, are generally welcoming to new people, and if they form a good impression, can be inclusive to their presence for an indefinite period of time. 

cariocas are social individuals who generally love interactive situations and are intrigued to learn about others - often seen laughing and in conversation with a diverse group of locals and visitors, cariocas are very receptive to new circumstances - this 'community' way of thinking extends well beyond  familial ties and personal relationships, and carries into many casual relationships and interactions - customs and traditions are unconsciously used and remind others how much they are respected, appreciated, and loved.
