I think BumbleB might have meant (in the context of her reply) that some people haven't lost touch with siblings or parents, which is a very sad thing to happen.
Yes, that's how I read BumbleB's post too. To me a "normal" family is simply a family that strives to keep in touch, without judging each other. To me 'family' can be more than the "Mum, Dad and 2 kids" from the nuclear family
https://en.wikipedia.org/?title=Nuclear_family . Perhaps .... perhaps IF 'nuclear' and 'normal' were interchangeable in BumbleB's post, then perhaps there's some concerns. But BumbleB did not use the word 'nuclear' so I am having trouble seeing any offence.
Please Gillg, please please don't read too much between the lines as I am quite sure there's many family groups who would prefer to be known as 'normal' families and who may well include adopted and/or fostered children within their family, or include within the one household, grandparents, cousins, and other family members under the one 'umbrella' expression 'normal' family. To me, born and raised in rural New South Wales, Australia, post WWII, .... we were a normal family, .... we kept in touch ... we still keep in touch .... Our normal family included grandparents, great aunts/uncles, parents, aunts,uncles, brothers, sisters, fostered brothers, fostered sisters, cousins and others.... And at school there were many other family groups of similar structures... all normally living as part of the one household per each group.
So, sorry you are offended by our fellow RChatter's word, but I am quite sure BumbleB does not intend to cause any offence.
So, simply put I don't read the word 'normal' as an emotive word in BumbleB's post.
Cheers, JM
