Who cares where they are - you will not be needing them.
In my glove compartment
in the freezer
In your panty drawer under the dog leash and the handcuffs.
Hopefully, you've still got them on
I hid them.
Don't you remember? You gave them to me, and now they are in a zip lock bag for my enjoyment. And no, you can't have them back.
BTW: I'm missing my underwear: any ideas?
They are really lovely, I am wearing them and you are not getting them back.
