Some of the things that are similar to out world would be some rules! Our society also has rules. Another similar rule would be that China can also only have two kids! You are also aloud to adopt children and treat them like your own.
Some things that are different once again would be the rules. In the Giver there are a lot of rules. for example you can only get a bike at the age of 9. You'll also be giver a name at the age of 1. In the real world you have freedom and you are aloud to do whatever you want. For example you can ride a bike. Whenever you want and you also have to have a name when you're born.
