well said nacchi. i agree with you 100%.
i am in my mid 60s. self and missus are planning our retirement. have told the kids, including the eldest one who is planning to have an 'in law' apartment in his house, that we will not stay with any of them. maybe if it works out, live close by, but would prefer our own and when unable to take care of ourselves, ensure to be admitted to a home, with professional care. we are careful to set aside money for that.
even with your kids, one has to adjust, as it is only fair, that it is THEIR house and we have understood ourselves to be thoroughly independent of thought and habits.
with modern communication tools, it is not an issue to be in touch with your loved ones on a daily basis. that is probably the only imposition we can do to them ie daily chat on skype, iphone or such. apart from that, i do not see myself, nor does the missus, of anything dependent on the children. we have also told them, on emergencies, we will come and help out with the babies, but not full time. as we have a life to live too, and we have done our share of nappy changing and baby bathing
