Screw it you think. You've been through a lot today, and decide just to call in sick. Besides, last time you went to work you were nearly killed by a lawn gnome.
You pick up the phone, to call in to work.
"Hello?" Your boss.
"I'm sick, I'm not going to be able to come into work today."
". . . Is this a joke?"
"No I'm really sick! It's!" At this point, you realize you did not change yourself back to an adult before calling.
"Erm. Yes." You try to lower your voice, and give your boss your name. "I'm very sick, it's why my voice is so screwed up. I'm afraid I won't be able to make it in today."
"Riiiight."
"Anyways..."
You hang up the phone, before your boss could object to your sickday.
Well, you have the day off. You'd love to spend it relaxing, but you're pretty sure fate will intervene soon enough sending you on some death-defying quest to get yet another one of the books.
However, you decided to go ahead and tempt fate, and just sit down for a moment, and rest.
