Just joined here and read your thread about your friend .
Sorry to hear about your loss . Losing a friend no matter how long you have known him/her is a real bummer . A friend of mine who I knew way back in High School (back when Led Zeppelin , Doobie Brothers , etc. were at the top of the charts ) passed away suddenly back in October in front of his son . It's still a shock to me and I know what you must be feeling right now .
