Your girlfriend had a bunch of idols lined up in the box all of which seemed to have been waiting for stimulation outside of maybe a random earthquake jostling them around. You picked one of them up and asked "So... how do you use an idol? Do you rub them or something?"

You might be able to run away, but you were feeling kind of freakish and desired some way to be somewhat normal. The Idols were just Idols, and it would be hard to interpret what they wanted.
