most cariocas are very social and expressive communicators that at times talk loudly, interrupt each other often, and use physical gestures to emphasize their points in a conversation - whether waiting together at the bus stop or in line at the bank, amiable chit-chat is an expected and normal part of the culture, and the expectation is the same even if both people are complete strangers.

more often than not, these conversations will range from common pleasantries to personal stories that go into surprisingly specific detail - to an outsider, it may seem that there are no limits to what can and cannot be shared and with whom - however, while these informal intimacies may give this initial impression, there are indeed clear and defined social guidelines and limits for this type of communication.
