Invisible/Girl: Order a pizza
From Create Your Own Story
You have also been wondering what it would look like if an invisible girl swallowed food. You call the local pizzeria and after half an hour of impatient waiting, the doorbell finally rings. However, only now you realize you can't really go pay the delivery guy. But that's not what you were planning to do in the first place anyway, was it? You open the door, and watch the poor guy step in and look around nervously around the empty apartment.
"Umm, hello?"
The guy is quite young, probably nineteen. He doesn't look too bad. You close the door and he turns around, now clearly frightened.
