You and ellie had fighted alot before, and argued Over some things, One time she saw you in the store with her (you didn't notice she was there), BUT she noticed you, after u finished shopping and you walked outside you suddenly saw Ellie , she was already waiting for u outside

she speaks in an aggressive tone

"Well...well..welll...Look whos here"

she chuckled after saying this , she was looking up and down at you in a mean way
