Don´t go to the province, everyone is "papá" or "mamita" there.
I was doing an interview for a documentary there, and the person being interviewed (who is a father) described a conversation between himself, his son and a nurse in which everyone was refered to as "papá"--his son refers to him as papá (logical) the nurse refers to him as papá (ok) and he refers to his 8 year old son as papá (ugh). Very confusing.
