  2. CandleImageAcquainted for nearly 33 years, you are still my hero, my rock, my best friend and the one loss I will never overcome. You were the most engaging, lovable human I have known. I miss your laugh attacks, and the ones you gave me. I miss your confident booming voice I could hear from the other end of the golf course. I miss your sarcastic one-liners and your photographic memory of annoying jingles and factoids.
    Life will never be the same for we who knew you.
    I remain your best friend forever.
