It is amazing how the thought process works. What is great for you might worth dime for your parents. The generation gap exists, seeing the world in a different lens.
You might think you have achieved everything in life but for your parents, you are still not settled. Settling down means getting married, having kids and ownership of a house. This ideal definition of being settled has been passed upon generations.
Few lucky ones survive this pressure and lead a life on their conditions while others succumb to settling down with the blessing of elders.
