Everyone has friends. And everyone likes to have a good time with their friends. But everyone also had that one friend that is always a good time no matter what. For the nights when your plans are kinda shady, and you have no idea where you will actually end up, everyone needs a "yes" friend.

You need a (platonic) plus-one to a party where you don't know a lot of people? Bring your, "yes" friend." He or she is up for a potential open bar and meeting new people any day.

You're going to the bar, and you don't know whether or not to expect a good crowd? Bring your, "yes" friend. They can make conversation with one person or one hundred people, no problem.

You want to try out that restaurant around the corner, but you don't want to go alone? Call up your, "yes" friend, he/she will always make good mealtime conversation.

Here are six ways you know you've got a true "yes" friend by your side:

1. You and your yes friend are perfectly platonic.
Whether or not you are the same gender, people make jokes that you are buddies and attached at the hip. No, you are not dating. You just know that no matter the situation, you can rely on your yes friend to make the best out of whatever situation.

2. Your yes friend doesn't ask for details.
Give him or her a time and a place, or sometimes just a time and an outfit suggestion, and your yes friend will be there. As long as they are dressed sufficiently, that's all they need. They don't pry about who is going to be there to weigh whether or not they are cool enough, they just show up. They don't need a preview of what you're going to do because they know whatever the two of you do together can usually end up as a good time.

3. Your yes friend gets along with everyone.
The yes friend is a special breed because he/she gets along with everyone. You are out having a low-key night and bump into some high school buddies? Introduce them to your yes friend, and they're making small talk and having good conversation in no time.

4. Your yes friend has their own friends, too.
The yes friend is not just a follower. He/she adds to the go-with-the-flow plan too! The yes friend is constantly bumping into his/her own friends and introducing you to new things! You want to check out the new sushi restaurant? They know another cool one you might like too! You don't have any plans for the night? Call up your yes friend! The relationship goes both ways.

6. The yes friend doesn't judge you.
The yes friend is here for you in the best of times, and the yes friend is here for you in the worst of times. Your yes friend will be there for the nights that are just a flop and don't turn out. And the yes friend will be there for you times that magically come together by coincidence. No matter what, your yes friend makes the best of your times together, completely free of judgement. Their yes to your invite comes with no expectation beforehand. You never have to entertain this friend, and they always understand why you did that one thing that one time with that one person who was kinda sketchy. No need to talk about it ever again.

This also means that your yes friend does not expect every single night to be the best night of their life. You are totally allowed to ask your yes friend to do aimless and boring things like watch movies and binge watch Netflix. Because yes friends need Netflix, too.

7. Your yes friend knows when to say no.
Though they are known for their ability to tag along and go with the flow of things, the yes friend also knows when to say no. This friend knows when to cut you off, or cut themself off. This person also knows when they seriously just will not enjoy the activity you want to do. In this case, your yes friend will honestly admit to you that they are not interested. And you will accept the decline because you understand they are super-cool the rest of the time.

8. You and your yes friend love doing things together.
This is your up-for-whatever (insert Bud Light commercial reference here) friend. Some of the best and craziest times will happen with this friend. As well as the worst and laziest. And that's OK.

The yes friend is a special kind of best friend. It's a no-strings-attached relationship that is based on the fact that it is so simple for you guys to tag along with one another.

Eventually, your friends start to recognize your yes friend and you grow to appreciate this friend more and more. As time goes on, you and your yes friend might go weeks without talking very much or seeing one another. But there will be other weeks when it seems like you spend all of your time together.

Nonetheless, your yes friend is not one to be forgotten. You can always expect him/her to enjoy their time with you as much as you enjoy them ... and what more can you really ask from a best friend?
