Ellie was one of those popular annoying kids in a group of girls just like her. Except the girls were all over her. So when she noticed you weren't all over her like the others, she decided to talk to you and annoy you. She taps on the side of your shoulder multiple times, repeating:

"Ma'am, ma'am, ma'am,"

Until she finally asks:

"You got gum?"

With a smirk all the girls flaunt over. She thought she could win your heart just for fun.
