How very sad Fairydoll I too never met my paternal grandparents. My GM died just before my elder sister was born, and as she had 3 boys and no daughters, she would have loved us. My dad's dad was apparently chased off by my dad, after he attacked dad's mum [his wife,my GM]he chased him down the street with a rifle kept from his war days! How true that is though, I don't know
I too grieved for my GDad, as he was alone, living on Isle of Sheppey, when my mum spotted him in a shop in Southend and said to my dad "that's your dad isn't it?" So they were reconciled, must have been 40yrs later! He died shortly afterwards, got knocked down, so I never got to meet him, as I was living in Africa at the time.
I do 'Healing breathing' in my yoga classes and I always think of my granddad John, as it turned out he was a healer and a member of a spiritualist church. My dad couldn't believe this of his dad, but I wonder if it was the estrangement that led him down this path, being cut off from his 3 sons & never getting to meet his GC. Of course in those days there were no internet, mobiles or anything like that, so if you lost touch with your family, that was it! Funny how my mum spotted him just before he died, after all those years apart!
I save some of this GN posting, mostly mine, but sometimes, like this one of yours Fairydoll[hope you don't mind] showing the sorrow & destruction estrangement brings. It's only saved in my GC memory boxes, so that one day, not only will they get to know how much I loved & missed them, but also their family history on their mums side, that she couldn't tell them. I also have a copy for myself, that I hope my ED gets to read one day and to then fully realise the enormity of what she has done to us; her mum, sister & her little girl, my precious GD [my GS has his dad & all his paternal family, so not as effected as my GD]
Needless to say why I hae not posted for a while, I have been read though and totally understand your post regarding being upset at not seeing as much of your Son as you'd hoped Smileless enough said.
Hope your check-up goes well today Celebgran and they find nothing they can't fix quickly for you.
Love to all the estranged posters on here 
Also to those not estranged but come on here to give us some encouraging words of support and sometimes wise words to help us through our dark days, of which there are many!

, as you've said 'haven't you been through enough'; yes you have and more than your fair share IMO
I had no idea and to think I've only just found out now they're not making it anymore[anger].

how can I make Rhinestone's Coleman reports big enough to read. I'm on a lap top so can't do that finger thingy where you can stretch something out to make it bigger. Oh dear, not sure this post makes much sense either.
