Oh, yes, you would definitely know these feelings. When my grandparents moved out from Yorkshire they had six kids in tow, and left family behind. They were given an opportunity to record a three minute recording on vinyl of them all singing happy Christmas - you can here my six year old Mum saying 'Happy Christmas Granddad!' in a Yorkshire accent (she doesnt have that anymore thank god - my grandparents never lost theirs). They listened to it so many times that the vinyl was worn and crackley as anything. They'd only see their kids once more in their lifetime and their grandkids never.
Oh god I've set myself off now!
