Old Letters & Cards

I just spent the last 3 hours or more sorting through letters and cards I received from friends over the years when I was going to college and uni here in Perth... 1987 - 1992... it made me realised that we used to write a lot of letters, cards and postcards back then... reading through some of the letters made me realise that there are gaps in my memory that I took for granted... like why did a 10 year old friendship just suddenly died or what was the reason that I stopped being friends with someone and what prompted me to reconnect with them and then let the friendship fell away... questions, questions and more questions... most of the correspondences are kept... this exercise has yield one positive outcome, memories and the resolution to 'hunt' down some old friends I have lost touch with... ah... the benefit of hindsight and some form of maturity... =p
