Please tell me if you think this is a supid idea. Read info to answer. Plzz

Okay so this girl at school who hates me for no reason said that if anyone she hated wore the same colour dress as her she was going to mess it up. So the colour is blue my and her favorite colour but ithink its a pretty stupid thing and makes her sound kinda insicure cuz to me it sounds like she doesnt want anyone to look better than her in a blue dress. Stupid to me yes. Please tell me what you think. Leave comments. plzz
