HM if there is any positive aspect to view here it is the fact that your dad lived a long and full life. You carry and pass all knowledge and lifes lessons that you learned from him down to the next generation and so on. I think that being able to lead a life to the fullest is truly a blessing from the big man. I also think it is safe to say that you have gained many brothers here in a new age high tech kind of way but were here for you brother!!!!!!!
