My father passed away last Saturday, no one saw it coming, I didn't really get to say goodbye because of that. However, i had an amazing relationship with my father. We were both extremely honest about our feelings, there were no emotional blocks, we hugged, we laughed, we spent time together and shared. In a way he was one of my closest friends. I often told him how proud i was to be his son, and how happy i was to have a father like him. So even without formally saying goodbye, without a final "I love you" I sleep well at night knowing what we shared and how lucky i was to know and have him guide me through my life this far.
I love you Dad, and i will miss you forever.
