When I was in my early 20's, this song meant a lot to me; its like I always wanted to go and say hello to an ex who lived not far from me at the time... why did I want to do it? Just a knock on the door and a hello, then away home, but I never did :)

Now I'm older I realise there's reasons why exes are exes.. but when you're young you always think everything is forever :)
