Ohh I forgot to mention 2 things.

1 negative thing is u always always always get the blame for everything when your an only child.

1 positive thing is when your parents do pass away u get everything. No fighting with siblings over things (very morbid thing to say but its the truth and even my mum used to say that she found great comfort in knowing that when they died I would be able to pay everything off and be debt free with heaps left over).
