Reaching out to old friends
Making new friends isn't always as easy as reconnecting with old ones. Maybe over the years, you lost contact with your college roommate. Or perhaps you just don't talk to your cousin that much.
You could get in touch with them to check on them. Say how you've missed being able to catch up and express your desire to restart the relationship. It could be simple for you to get along with people from your old school, neighborhood, or workplace since you already have things in common. Talking about the old days might help you reconnect, and you might discover that you can build a connection going ahead.
