Cultural Tip
In Brazil, ‘Peça ajuda…’ is considered polite and slightly formal, making it suitable for strangers, teachers, or supervisors. Among friends you’ll more often hear the informal imperative ‘pede ajuda…’. Also, Brazilians value self‑advocacy, so encouraging someone to ask for help is seen as supportive rather than a sign of weakness.
