Many of us have that one friend who has been our best friend since childhood. They pretty much are family and everyone wonders how you are still friends after all this time. So many people walk in and out of our lives, especially during adolescence, it's very rare that we find a friend who is willing to stick with us for the long run. There are many positive aspects of having a best friend who has been there since the beginning. Here are just a few:

You never question whether or not you can trust them.

Meeting new people and making new friends comes with a lot of questions. One of the biggest concerns we have is if we can trust the person. Having a childhood best friend means that you never have to worry about them betraying your trust. They make us constantly aware of what a genuine friendship is and who is worthy of our trust.

They know us better than even we know ourselves.

Our childhood best friends have been there for absolutely everything, so they pretty much know exactly how we are feeling and why. You will never have to tell them when you are feeling upset, they automatically sense something is wrong.

They know exactly what will make us feel better when we are upset.

We don't even have to ask them to help us through the tough times because they do it automatically. Our newer friends will try to find ways to cheer us up, but only our childhood best friend knows exactly what will work.

The millions of memories will never end.

Since they have been there for everything, pretty much all of your favorite memories have been with them. Not only have you already had some great times together, but you will continue to make even more in the future.

If you ever forget anything, they probably remember it in detail.

One of the best parts of having a childhood best friend could be that, since they were there for everything, you pretty much have a second brain holding all of your memories. This makes it so much easier to remember every little detail of every little thing.

They know everything about your family.

Because you grew up together your families have pretty much combined together. Their siblings are your siblings, their parents are your parents, and their house is your house. If anything happens with your family you can tell them without having to explain who is who and how you are related.

You never need to tell them your life story because they already know it.

Meeting new people requires explaining who you are and everything about yourself. Generally you tell your life story because it is the only way people can really get to know you. Your childhood best friend never needs you to do this for them. They were there for it so they already know it.

They are as comfortable around you as you are around them.

You can always be yourself around them. You are never embarrassed around each other and there is never any pressure to be something you are not. Since they are pretty much family you don't have to worry about what they think and they don't have to worry about what you think.

You have made some poor decisions together and learned from them.

As we all know, everybody makes mistakes. If you have a childhood best friend, there is a high chance that a lot of those mistakes were together. That's because together you cause a lot of trouble. But you also learned a lot through making those poor choices and they have helped you to become the person you are today.

You can go without talking or seeing each other but if something important happens you know they will be there for you.

Everyone gets busy, people move, life changes, but no matter what, your childhood best friend will always be there for you. Although they may not always be physically present or readily available, when something significant happens in your life, they are the first person at your side.

When you are together it feels as though you are still kids.

No matter how much time passes, you can always act like children together. The friendship doesn't change much and you can act as silly as you would have when you were 11 without being judged.

You know you will always have someone on your side.

No matter what happens, your childhood best friend will always be your biggest support system. They will be there for you even when they don't agree with what you are doing because they know that you need them. Your enemies are their enemies and your passions are their passions. No matter where you go in life, they will be present without a doubt.
