You can keep a toy on the shelf and ignore it except for the times you feel like playing with it; that's fine for an object. But to do that with a human is to objectify them.
Example of someone objectifying another person:
''The women I know in their early 30s are just delusional,'' he says. ''I sometimes seduce them and sleep with them just because I know how to play them so well. It's just too easy. They're tired of the cock carousel and they see a guy like me as the perfect beta to settle down with before their eggs dry out … when I get tired of them I just delete their numbers from my cell phone and stop taking their calls … It doesn't really hurt them that much: at this point they're used to pump & dump!''
