A best friend is someone who is there for you through thick and thin. It's someone who listens and understands you. Someone you can call anytime about anything you feel you need to 'tell' or 'vent'. It's someone who will stand up for you in the times when you need it most, keep your secrets close, and someone you can trust with your life. They will support you in any decision you make even if it's hard for them. It's someone who is there for you as much as they can be and does and says whatever they can to up your mood in down times. You can be your COMPLETE and total self around this person without feeling uncomfortable. You can say or do anything, and your relationship never changes. Someone who literally feels sent from heaven to make your life that much easier. Someone who will do almost anything for you as you would do for them, and someone who loves you no matter what kind of stupid things you do. This person will always want the best for you, as you will always want for them. And as much as people change- Your love with a REAL best friend will never fade through all the phases of life and problems that come a long with it.
When I go through hard times, there is only one person who is there for me no matter what and that actually makes me better, that's my best friend.
