Sorry Milacron. I lost my dad in 1972 and even now I get a pang thinking about him.
What ever I have to say will sound trite because it's all been said before. You will griven so go ahead whether it's mild or devastating. Let it happen in whatever form it chooses to take. Hours or days will go by and then something will trigger a sense of loss. Sooner or later these will fade.
Sooner or later we all will be orphans. Dad would have been 100 this year and Mom 99. They weren't perfect but they were mine and I still miss them. I would have loved to drop an iPad or some other of today's marvels in my Dad's lap and watch him explore it, set it a side, scoff for a few moments, then take it up in irresistable fascination. He was that way when I gave him an HP35. He actually got out the math tables and checked the values the calculater gave against those on the page.
Mom would havbe been scandalized with shows like "The F Word", flabbergasted by home CNC quilting, and enthralled by her now many great-grandchildren.
Anyway, Sorry, Don. You're not alone.
