I would like to wish you the very best. But please don't make promises you can't keep. Because it builds false hopes which sooner or later collapses.
>You would be surprised to hear that my friends (girls and guys alike) don't believe me and think I am joking.
Not surprising at all. In fact I'm finding it difficult to take you seriously. Given how many mouths you have to feed. Your family will be really big which 2 parents + 2 parents + 2 kids(assuming) + you and your wife. That's almost 8 people. Maintaining a family of 10 people, their expenses, bills, health care is a costly business, Even if you have your own BIG home. Else add rents et al to additional expenses. Plus you have kids education + their expenses. And your own family expenditure. Unless you are earning really huge I don't see you will make it through.
Therefore even though you may want to. But still you may not be able too.
>>In their opinion, I don't know what I am talking about, and will not care about anyone once I get married. TL;DR, People, even daughters laugh at you when you promise to take care of their parents equally as your own.
They are just trying to deal with reality.
