I am not the only child, but I am the only son in the family and I am already feeling a little "out". It's quite unlike my pals with fellow brothers in their family, especially I am already on bad terms with my elder sister. With this issue, I already forsee I will be very much alone by myself with my own family and my in laws (if I have one even...) after my own parents are gone.
Just in case anyone is trying to digest what I am trying to say, I meant even if more children it is not a guarantee things will be better. Really depends on how life pave out for all of us and our children.
