When someone says thank you, who is it for? According to Dr. Sara Algoe, expressions of gratitude have a positive effect on the person receiving the message, the person delivering it, and even those who witness the exchange. These types of social interactions are crucial for building lasting relationships with romantic partners, friends, and coworkers.
“When we say ‘thank you,’ we’re sending a message to the person who just did something nice for us, that they are valued, that they’re seen, that the thing that they did for us was worth doing in the first place,” Algoe says.
Expressing gratitude is easy, and the research shows that the benefits far outweigh the effort.
