It is always good to have a best friend that you can go to whenever you are feeling down or want someone to go to. They are the ones who are there for you through thick and thin. Depending on how long you have known them, you could grow old together and create several memories together. They are the best people to surround yourself with as long as you get along well with each other and dont have a ton of drama.
My best friend and i have been there for each other through everything! There was one time when we got really mad at each other for a couple months but we got over it eventually and became close again. Closer then before. We have made so many great memories together and hope to stay best friends till the end of time.
