 But actually, old friends, research shows, tend to be happier than we think when we reach out to them. Same with family members. So reaching out to old friends can be really helpful. They tend to be happy about that. We can also join groups. So research has shown that we tend to have fewer group opportunities. We tend to do less in our communities these days. So if we can join groups and show up consistently to those groups, then that can be really helpful because the more that we're around people, the more they start to like us, right? And that's something called the mirror exposure effect.
