A purposeful exchange
Vy: Could you tell me what the tour includes?
Guide: It includes a guide and a snack, but not lunch.
Vy: Thanks. Is the route suitable for someone who walks slowly?
A useful exchange has a clear purpose: ask, respond, check and close. Use a polite question rather than an order when you need help. If you are unsure, ask “Could you explain that?” instead of pretending to understand.
