My long lost and unknown friend

I was standing at the counter, checking the appointments, when I was greeted by a tiny voice. "There you are!" she cried.

I turned and looked, and there was a chubby girl of maybe five or six. I had no idea who this girl was.

"I looked everywhere for you!" She exclaimed and threw her arms up in the air like she wanted a hug or something. I looked around. There was no one else nearby. She was talking, unfortunately, to me. Again, let me state that I had NO IDEA who this girl was.

"You looked everywhere for me?" I asked, hesitant.

"Yep. I has so much fun with you the other day that we came back to see you again, didn't I grandpa?" She turned and looked off to her left. There was no one there. Okay, now this was very creepy. "And I have something too!" She pulled a tiny scrap of blue paper out of her pocket. Looked like a piece of a lottery ticket. "Read my shirt!" She commanded.

"Alligator farm zoological society." I said the words blandly, hoping to wake up. This was a dream, right? No, I was at work. Had been at work, for a couple hours by now.

"What's a zoodaloddico society?" She asked, putting the piece of paper back in her pocket.

"It's an, erm, animal studying thing."

"Oh." She gave me a hug, I responded reluctantly.

"Erm, I need to go now. I have, erm, things to do." This creepy child who talked to her non-existent companion was unnerving me.

"No you don't. You don't have anything to do right now." She said, very seriously.

"I have to go to the bathroom." I lied.

"I'll come with you."

"No you won't. You stay here and wait for your mom or something."

"My mommy is dead." Ouch.

"Okay, then stay here with your grandfather then." The grandfather I couldn't see.

"He's dead too."

"But you were talking to him!"

"I know."

I rubbed my eyes and then, when I looked up, she was gone. I swear I wasn't sleeping. The night continued like normal after that, I went home, and went to sleep.
