[单项选择] When you were small, all ambitions fell into one category: when I am grown up, I’’ll go up in space. I’’m going to be an author. I’’ll kill them all and then they’’ll be sorry. I’’ll be married in a cathedral with sixteen bridesmaids in pink lace. I’’ll have a puppy of my own and no one will be able to take him away.

A determination to be better adults than the present incumbents is fine, but to refuse to grow up at all is just unrealistic.
Right, so then you get some of what you wanted, or something like it, or somet
A. Their wanting to grow up.
B. Their not wanting to grow up.
