They are the people closest to your heart, a comfort to your soul, your biggest fans and your most honest critics. They have a speed-dial button on your cellphone and a place of honor in your heart. For true friends, you don't always have to be strong, chipper or perfectly styled – they know all your faults and like you anyway. Just tell your best friends how important they are to you and what you never would have achieved without them. Here's to memories and party nights, to things in common and to differences, to laughing together and crying together. Here's to friendship!
