Ah...those were the days! Doing solo visits to various foreign living relatives' towns started a rumour that "we" weren't getting along all that well..... and various improvisations on that theme. Eventually the grapevine brought that back to us. And we decided to let the rumours be, and offered minimal explanations to "why the solo visit ?". When children grew up and knew a thing or two (from watching soaps in America), and get asked weirdly worded questions by some distant Aunty, one devilish child had gone and mentioned "joint custody" .... rationalizing that all parents have joint custody.
