After all,eight was special birthday,another decade lived or endured just you chose to look at it.

After all是副词 eight was special birthday是插入语 可以看做是从句 another decade lived or endured just you chose to look at it.
这个是主句而且是被动语态目的是为了强调 其中another decade 为主语lived or endured 为谓语 chose to look at it.是从句it指代的是lived or endured 。不知这样你明白了没？

意思是： 毕竟,八是特别的生日,再多活十年或熬过来的,你如何看待它。
