If there is one thing that watching F.R.I.E.N.D.S (for the millionth time) has taught us, it is that your friends are your chosen family (and that joey doesn't share food!). They are there for you through thick and thin and have seen you at your best and put up with you at your worst. But like every relationship a friendship has a process of evolution.
A new friend gets to see a more spruced up version of you, but your old friend knows you inside out and the pretence of sophistication is completely unnecessary! But eventually when you let your guard down your new friend gets to see another side of you - and is gradually welcomed into your core group of old friends. This hilarious video shows just how we behave with our old friends vs our new friends.
