A best friend is someone who sticks up for you and stands by you no matter what. They are kind smart, sarcastic, and will always cheer you up. No one can replace your best friend.

A friend everyone wants, but few have. Some search their whole life for a best friend and never find one. Some find one when they are very young. If you are lucky enough to get one keep them. Many people don't have best friends and lay alone every day wishing for one. If two people are best friends they are always happy together. Sometimes best friends get in fights, but it never lasts long. If you are ever lucky enough to find a best friend that lasts longer than 1 month you must be a great person, and a great friend. If you never find a best friend (like myself) you probably should stop trying because it's obvious you'll never find one. It's ok though because then you have one less birthday and Christmas present to buy... it's also one less that you'll get. It sucks not having a best friend, especially when it's the one thing most people need. You always feel alone.
