What is most closely the meaning of the term “bids” as it is used in the passage below (paragraph 10)?

Paragraph:
Throughout the day, partners would make requests for connection, what gottman calls “bids.” For example, say that the husband is a bird enthusiast and notices a goldfinch fly across the yard. He might say to his wife, “Look at that beautiful bird outside!” He’s not just commenting on the bird here: he’s requesting a response from his wife—a sign of interest or support—hoping they’ll connect, however momentarily, over the bird.
