So, what's the best way to respond to an 'okay' that keeps the dialogue flowing and maintains a positive tone? Should you simply acknowledge it with another 'okay' or is there a more engaging alternative? Perhaps a follow-up question, a compliment, or a statement that builds on the previous topic could be more effective.
