At some point you reach that mythic age known as "adult". Sadly, you discover the ease with which friendships formed when you were younger seems to have escaped you. You might have a group of friends from university or high school, and a few friends from the jobs you've had. But, what are you supposed to do if you want to meet friends now? You could always go back to school, but I'm assuming you don't have 100k and two years of free time?

First, let's examine why it was easier to make friends when you were younger. Sure, cell phones might be the reason you can't make new friends at a bar. But people tend to be looking down on their phone because they either don't want to speak to strangers, or don't know what to say to a stranger if a conversation were to occur. The real reason friendships were easier to make in schoolis you had an initial reason to get to know somebody. You were reading the same book, working on the same problem set, or had the same boss. So with that in mind, let's look at fun, grownup options to have reasons to speak to strangersin the real world, unplugged and off-line.

1. Outdoor workout groups:

There's no limit to the number of workout classes on offer. They can be great for workouts, but not as great for building connections with other class participants. This is because they're designed to create a connection between you and the instructor, not you and the other participants. However, there are a ton of great free workout groups that meet up in public spaces and bang out the workout, and they're usually free. My personal favorite is The Rise. They have chapters in a bunch of cities, and the concept is the same. Volunteers get people together in the morning before work for runs, circuit training, and sometimes Yoga. Trust me, the first time someone challenges you to a no holds barred push up competition, a friendship is formed! Look around though, most cities have some kind of a version of this.

2. Interest groups:

This requires a certain amount of self-reflection, but whatever you're into… there's a group for that.. Are you into rock climbing? There's a meetup for that. Do you want to get into rock climbing, or at least pretend to be into rock climbing, or at least go and talk about rock climbing? You can still go! If you're interested in something slightly more intellectual, there are many interest groups you can join in on.. My personal favorite is Young People in Foreign Policy. No, you don't have to be a diplomat to join. Or be particularly young. All you need is strong opinions or be willing to listen to people with strong opinions.Listen to a paneled of informed experts talk about the future of the European Union for an hour, then be handed a glass of wine at the following event.I assure you, you'll be able to make a new friend. (Or a lifelong enemy!)

3. Alumni Clubs:

If you went to college,even if you didn't graduate, you can join an alumni club in your city. What's great about these groups, is they tend to attract people from the 22 year old right of school to the 75 year old who has been coming to these events since the Carter administration. My college, for example, has book clubs, a lecture series, and a general networking event this month alone. Trust me, your school probably has something as well.

4. Take a Class:

You don't have to go and get an entire masters degree just to recreate the fun of making class friends. Anytime you have a given topic to discuss you're more easily able to make a connection. If you fail, you still learned something. New York City has an ocean of options to choose from but some of the best are offered by the 92nd Street Y.. Want to get less terrible at painting? Find out what Bridge is? Create ceramic art for all of your relatives instead of buying them something. The 92nd Street Y has all that, and potentially new friends to boot.

Tired of going out to bars and being just one more person staring at your phone? Stop going to bars, have something to look at other than your next drink.
