It was a very cold day outside. Although Erin really loved the Hogwarts grounds, there’s no way she’ll risk her health in that windy and cold weather. It is a good time to finally have a stroll around the castle. She’s never really explored the inside of Hogwarts. She just hopes, she’ll bump into someone who’ll be willing to walk with her, or maybe stay in one place. She’d always fancied the stories she overhears at the common room about the different magical stuffs around the castle, like the Room of Requirement or the Mirror of Erised. She wanted to know it first hand or maybe discover something no one had ever known. That would be a great stroll.

She went up and down the moving staircases, playing with it for a while then going up and up and up and there at the fifth floor, something stole her attention. It was the girl’s bathroom. She definitely needs a pee. That may be the best place she’d ever come up so far on her stroll. She hurriedly pushed open the door.

No one was there. Erin doesn’t like a deserted room, that’s why she always stays in Hogwarts grounds. But, she really needs to pee right now. She gathered the courage and entered the bathroom. Seconds later, she’s done when suddenly…

BOOM!

“Who are you?” Erin was surprised to see a GIRL! Why would she be shouting by seeing a girl in here? This is the girl’s bathroom. Hastily, Erin peeked behind her back to see if there was a ghost. She can’t stand ghosts. “I thought you’re a ghost,” lowering her voice and sinking her head below. "I'm sorry. And hey, are you first year too?" Judging by the looks, she's older than her.
