How did Chi end up in the trash? In Chobits, the protagonist finds Chi discarded with trash behind some house. 


   One would think a product of a secret project like that, containing some extremely important secrets, would be at the very last disposed of in a responsible manner, and not just thrown out. 


Maybe I wasn't an attentive watcher but I never spotted any backstory as to how she ended up there. Does the show explain it? If not, are there any viable theories?
In the manga, Chitose Hibiya mentions that she hoped someone would find Chii and give her all the things she was missing (e.g. Love). Chii's memory was wiped because she was sad, so this was an attempt to start over from scratch without any of her painful memories. And this also means not knowing anything about Chitose.

So Chitose put Chii in the trash so that Hideki would find her.
