What's happening: Many of us spent over a year stuck in our homes by default — not having to decline social engagements we weren't keen on. Now it's time to re-learn the fine art of saying "no." "I don’t know that there’s been another time in modern history that we’ve all had time to go home and think," says Mark Leary, a psychology professor at Duke University. "We’ve realized that there’s a certain portion of our social interactions that were never all that rewarding." "But now there’s pressure on people to come back out just as there was pressure to stay home," says Rebecca Adams, a sociologist at UNC Greensboro. "We'll have to accommodate more and more casual relationships." And that's tiring.
