It is always devastating to lose a friend. Even harder to lose one so beloved. You ask all the crazy questions - why him? Why so soon? Why are we given so little time with the special ones? And, that leads me to my point.
Live each day to the fullest. Spend time with those you love. Don't pass up an opportunity to be with them whenever you can. Time is short. Life is fleeting. None of us knows what tomorrow will bring. Revel in your time together. And cherish the memories of that time.
I won't say "rest in peace," Roo, because I know you are running through the endless green fields above with all those who have gone before you.
Until we meet again.
