I was shocked recently when my mother used the word 'assimilated' to refer to the process her family/my family has gone through. All these years I have known her and not one mention of such a thing. I never realised that she was aware of this transition. Of course she was, it was so obvious it didn't need talking about.
To me it is clear as day. We just weren't here before the mid 1930's, apart from one grand parent. The rest were in other places. It's a long time ago now, but it wasn't when I was born.
