The easily mistaken twins

Avery Miller stood alone, lost in thought, when suddenly a pair of hands, belonging either to Jessica Wilson or Sarah Wilson, appeared before her eyes, snapping her back to reality from the depths of her memories.

"Avery, are you feeling okay?" asked the person in front of her, whether it was Jessica or Sarah, Avery couldn't initially tell. 

Avery lifted the corners of her mouth into a brilliant smile and replied, "I'm fine, don't worry. I was just wondering whether to attend class tonight or to go…"

"To the street food stalls!" exclaimed the person entering from the balcony, either Jessica or Sarah, in perfect unison with the sister in front of her, then they both joyfully hugged Avery, exclaiming how great that idea was.

Avery, feeling slightly embarrassed by their enthusiasm for food, remarked, "Seriously, you two look so alike already, how many times have I told you to wear different clothes?"
