Two words I suddenly notice I'm coming across these days are "fun and friendship." Together. As in, join us for fun and friendship, or sign up now for fun and friendship. I often see this with adverts for classes to join or fitness events, or large group activities that encourage a large number of people.
I think classes and activities are perhaps the perfect way to meet someone new, because you're doing something you enjoy and that naturally makes you more open when you meet others. Also, you'll be surrounded by other people, which is a requirement for friendship. (Meaning: you have to actually meet them and talk with them in order to become friends with them.)
Most of the time, I like these little "fun and friendship" adverts, but other times, I wonder if people get the wrong idea about them. They may sign up for a class that promises "fun and friendship," only to go once or twice and then feel bad about themselves because they didn't meet anyone they thought of as a friend.
If you're one of those people who has joined something you thought would help you make friends, only to find out that it didn't help you to make friends at all, take heart! First of all, know that making friends takes time. Next, focus on just getting out and enjoying yourself. Learning to be more open will naturally attract new people to you. Also, give it time! You will meet new friends when you get out and do something new. But when? It's different for everybody. Don't give up after a few times just because a class promises fun and friendship. Fun and friendship will come in its own time.
