No matter what, your family has to put up with you (and I mean that in a good way.) Your family shows unconditional love and support without question since the day you were born. No questions ever asked, they just have to because they are your family and they are always going to love you. But your friends are different. You aren't born know who is going to be a text away and who will be a part of your life who will also show you unconditional love and support. Your friends are the family you chose for yourself.
You learn who you like and who don't, and who you want to spend more time with than others. You pick who you want to share memories with, who you want to help you with your homework or drama or just through life in general. Who will sit in your dorm for hours doing nothing but spend time with each other? Who will go on hour long drives just because you can? Who will accept you at your worst and best? You love them like you would love family and they do the same for you. Sure, some of your chosen family comes and goes over the years as you grow up and go your separate ways, but that can happen with your family as well.
Chosen family isn't as permanent, but it sure does feel like it could be at times. Nothing is ever certain. You have certain people for certain points in your life but there are some that you know will be around and be a part of your family forever, and they are there because you chose them to be. You were so drawn to them as a person and their personality that you wanted to spend your time with them. You wanted them to be apart of your life.
Those that you know will be your chosen family forever is one of the best feelings you will ever have. They are there when families not (or if you don't want family to be there.) They are there when you cry and are there to make you laugh until you cry. The concept of choosing who is apart of your life and who gets to be with you when you need it is something that is so unique and so special. You get to share your life and moments of your life with people who want to do the same with you. Some you have known longer and some you may have just met but it's one of those things that you just know when it happens that you have met your chosen family.
