Some things can be shared, but some things are simply indispensible that totally cannot be shared.
These include things like EDUCATION, TIME, MONEY, EFFORT......
Whenever I think of the education costs, I will get headache... and hey, every parent will hope that their child can get into university right?.. and not to mention, along the way, they will be influenced by peer pressure to have things like mp3, HP, laptops, and watever 3Gs, 4Gs that keep evolving... These cost lots and lots of $$, which cannot be 'predicted' at one glance...
Of course, the downside of having one child is that they can be very lonely.. so really in a dilemma...
Me myself come from a 4-kid family... no lack of siblings rivary, quarrels, and the huge burden of taking care of my 2 younger siblings... But luckily my parents worked really really very hard and save up a lot in order to send his kids to university... Along the way, we had to give up lots of things such as toys... and everything is a share-share thing...
