You'd been invited to a sleepover party at Hello Kitty's house for her birthday. She had invited all her friends and had planned lots of activities she had told you over the phone. You get out of your car, holding your sleeping bag, and walk up the gravel path to her house; you ring the doorbell-- and after a few seconds, Hello Kitty answers the door--you can see everyone inside already in their pajamas eating chips and drinking soda. Hello Kitty smiles at you. "Hey, come on in."
