Taking care of parents

Till last week, i was in a wrong assumption, that after a certain age, we need to take care of our parents. But it is not a must. My dad taught me this in reality. Now a days, most of the parents are financially strong and they have their own house/farm and they want to be independent. They do not want to be a burdon to anyone in the family. They want to cook, visit doctor, go to temples etc on their own. If needed like, while getting hospitalized or in need of immediate attention, with respect to manual help only, they go for their family attention. They never want to see their kith and kins worrying about them. My dad told, me that even I should not depend on my son / daughter on my old age. As far as possible, he tells me that he will not disturb his son/daughters financially or for any manual help too. In that way, there is no obligations are created among the human kind, he says. Same way he also lives and demonstrates his principles too. What a great man my dad is!!!
