“A small signal can have a huge effect,” Walton says. “But the deeper thing to realize is that you can’t just give a cue once. This is all about establishing relationships, conveying the fact that I’m interested in you, and that all the work we do together is in the context of that relationship. It’s a narrative—you have to keep it going. It’s not unlike a romantic relationship. How often do you tell your partner that you love them? It may be true, but it’s still important to let them know, over and over.”
