Dawn,
Personally, I'd offer the opinion that the MFRC is an attempt to officially formalise the support network that used to exist "once upon a time" ... (i.e. neighbours would help each other, the unit "rear party" would go out of their way to help ... etc.)
This week while I was a liaison officer somewhere else, I personally overheard a senior officer promise to shovel the driveway of a young captain while he was in Sri Lanka ... returning the favour for when he, himself, was deployed previously ...
My friends have told me stories of the good old days when the Rear Party was kinda like a Big Brother - even shovelling snow, car-pooling the kids to the hockey arena/swimming pool, helping to buy a car when the family clunker rusted out, sharing teenaged kids as babysitters, and so on ...
My mother has told me about how the families would all get together during the Second World War, too ...
Oddly enough, I can still remember when I first enlisted and was welcomed to ... "The Regimental Family".
Best of luck to you - and don't forget the old saying: "If you're not part of the solution ... ha!"
P.S. (I see that Dianne posted while I was typing ... so I can only guess that she and her hundreds of acquaintances are the only ones that "get it", while thousands of others don't ...)
