This is a very basic question, but my English brain has a hard time distinguishing between second person plural and third person plural. I know second person plural is for example: "You (guys) are from Spain" which would be "(Vosotros) sois de España" in Spain or "Ustedes son de España" in Mexico for example. For third person, it would be: "The kids are from Spain" which is "Los niños son de España." However, I came across this sentence which I *think* should be second person plural, but not really sure: "You (tú) and the children are from Spain." In Spain, would you say "Tú y los niños sois de España" or "Tú y los niños son de España" ? That is, is "tú y los niños" second person plural or third person plural?
