I just got chatting to twins, aged about 16. Their parents split up when the girls were very young children and one moved to North America and the other stayed here. One twin went with each parent.
I am really quite taken aback by this as although I don't know how old they were at the time, they must have been very young as they said it was all they ever knew so didn't seem strange. I think they had a lot of holidays together and did seem close but it just struck me as an unusual thing to do. Do many people split siblings at a young age in such a situation, never mind twins?
I don't have a point to make but just found it interesting.
