We knew David for 20 years. We live in the same complex and we were very saddened to hear of his sudden passing. Our condolences go out to David's family.
I was very sad to read that Dave has passed away and unexpectedly. I am very sorry for your loss. He will be greatly missed I am sure. I can sympathize with how you feel having lost my brother Warren in 2000 and my sister Madeline just before the New Year in 2012. My deepest sympathies to your families.
