Nigel,

I usually don't understand people very well even if they're not angry, so I can't say much about what may have happened. However, I can say that my uncle two years ago, recently widow(er?)ed at that time, was very cross with my mother, to the point of severing all ties (indeed by telephone). The last few months, however he has sent birthday and Christmas greetings. So, apparently there's always still hope that in time things may change.

Bye,
