Ok,me and my best friend christina were going school shopping together. Christina was trying on clothes and i was garding the door.She asked me if i was making sadow puppets and i said no.Then she started to freak out because there were these white passing by the mirror.I was all like it's all in your head!She got out and it was my turn,and right when i looked in the mirror there were shadows.And i few weeks before we were looking on the internet at scarys stories kinda like these.A thing popped up about two way mirror and how to check for them,so she reminded me of that and we decided to check.And to our suprise it was a two way mirror which meaans that people our watching u through a diffrent mirror.We told the clerk guy and he smashed the mirror and the manager was watching us!
