I don't even know how to respond. I've been laughing visualizing it all. That singles player is, er, too serious. Mixed is not for keeps particularly when you two just met. Can't figure out why he felt you needed signals. Like you can't see when he is running toward your half of the court and you would not just adjust.
Little did he know you're a good doubles player.
