What is the proper way to let a Spanish speaker know it's okay to use informal pronouns?
My daughter’s nanny is from Peru, and we speak to each other in Spanish. She always uses the formal pronouns and conjugations (Usted, etc.) when speaking to me. I would like to tell her that it’s okay to use the informal, but I don’t know the proper way to do so. What is the proper etiquette on this?
