personally, i think, the dil mil relationship is mixing oil and water.
my own experience is a good example, of even a silent mother, will find it difficult to live with dil. and i am 64 and of the previous generation.
today i am a fil, and i see, mrs K and my dil, getting along great. mrs K is extremely nice and appreciative of dil. which is responded in kind. the more mature mrs K has always taken the first step towards this warm up, after our son introduced his his future wife couple of years ago.
there is regular communication, as these live in usa. my younger children visit them every other month, and all of them being of the same generation, hit off great with similar lifestyles. i myself would find it hectic, and am perfectly contended, staying at my toronto home, though mrs K makes visits once every 3 months, and the son/dil visit us every 4 months.
all these visits are short and over a weekend.
anything more than this, i am quite sure, would create issues. as sharing the same household space, even with my 2 unmarried grownup children, is problematic. the children, think it is free boarding, lodging, laundering and cleanups. mrs K and self, are getting on in years, and do not have the energy to cater to such anymore.
re the old snapshot of 3 generations living together happily, personally i only have to wonder. if the old man is retired, he is already past his prime, and sitting at home, is nuisance to his wife. if the dil is working, the mil, has to take care of the house, the grand children and the old retired fogey. poooor woman. if i were she, i would opt for the peace of a retirement home, with maintaing ahousehold for just the hubby and herself.
my cousin, in his seventies and wife, recently spent close to a year, in usa, to take care of newly born twin grandchildren. it was very hard he confessed. while on one hand, they could be with their only son, the task of 2 infants, household keep, the vagaries of weather, all added up to a lot of stress. they could not wait to get back to india.
incidentally, here, the dil, who is a rajput, her parents did one shift of 6 months, and told their daughter, they cannot handle it. so i think indian parents go a long way to help out even their grown up kids, who really, i find, are not 'grown up' at all - when it suits them, they depend ontheir parents. otherwise, find them a nuisance.
i am seeing the retirement and old age homes in chennai suburbs - would not mind spending the winters there, for after all, i need is a company of 3 others to play bridge, and mrs K to watch TV, and some books from landmark. and prefer to be a part time grand parent - hold the grand child, pat it a few times, and hand it back to the parents to bring up
