Girls in hoodies with nails
Lauren walks to the bathroom counter, puts her water bottle down, and then uses the bathroom stall on the left.
The bathroom stall door on the right opens and a girl walks very fast to the bathroom counter. All you can see is what is reflected in the bathroom mirror. Her face is completely covered, she's wearing a red hoodie, and she put something in Lauren's water bottle. She wipes the top off with a paper towel and you can see in the mirror that her nails are painted light pink. She then exits the bathroom quickly.
The middle stall borages open and a teenage girl in a black hoodie, also covering her face, runs to the bathroom counter. You notice in the bathroom mirror that her nails are painted a dark red color. She grabs Lauren's water bottle, runs out of the bathroom, and dumps it in the trash on the way out.
Lauren then gets out of her stall and we hear her toilet flush. She goes to the sink and then begins to wash her hands. She noticed that someone threw her bottle in the trash.
"Well I am not digging it out of the nasty trash can. I will just get a new one." She said to herself.
