JennyInGucci how spectacularly obtuse are you?
It's utterly normal to move away from your parents' home town to work.
It's utterly normal to meet your husband or wife hundreds or thousands of miles from your parents home, while working or studying, and for it therefore to be impossible to live near both sets of grandparents.
It's utterly normal to start a family in your 30s, meaning grandparents are often all 65+ which increases the risk of health problems.
It's depressingly common to die before the age of 70, "average" life expectancy being exactly that - some people live into their 90s (my grandmother was 99) some die in their early 60s, as my MIL did.
It's also utterly normal for grandparents to have their own lives and move away themselves without this being indicative of a family feud.
In fact most feuding families who are "not speaking" seem to live within a few miles of one another.
Where I lived when Dc1 was born not one of my circle of friends made at NHS antenatal class lived within an hour of a grandparent - we supported one another. When dc2 was on the way we moved to live near the healthy, sprightly in-laws who were very involved, but MIL died and FIL is spending time with other family in another country.
Bloody hell some people lack imagination beyond their bubble.
DH and I manage fine between us because we can juggle work hours (one shifts over which I have a lot of control/ choice, including weekends, one flexitime office job in which 6am - 2pm is perfectly acceptable, as is 11am - 7pm). I might as well say how incompetent and unemployable or how selfish, egocentric and careerist must a couple be that they couldn't find flexible jobs like we have.
