okay, you don't have to be rude about it. but you can actually say to objects, "hey, object, you're another kind of object now."
when reading before bed last night, i couldn't remember where my bookmark was. so i just threw out my arm into space, let my hand find... something.
a drink coaster.
and—yeah. i just threw it in there. in the book. and it worked! (at least, i think it did. i haven't tried reading again today.)
