Good write-up! 

Don't be so much emotional guys, we're gonna be parents very soon and have to follow suit. Parents can never be selfish; otherwise, they will no longer be parents.

Parents probably enjoy far better working hard for the sake of their children and living a simple life than living a luxurious life and doing nothing for them.        

I belive they do not expect anything in return from us rather than our progress, prosperity and good health. It is just a foolishness if we think we can return. But we have to be grateful. That is enough I guess. 

Thank you so much my parents you gave me birth, raised me and worked hard to give me education. I will try my best to follow your path. Thandavat!
