You decide to tell Claire you're her sister's boss

You decide that it'll be harder for Claire to just blow you off as some random guy, so when she takes a break from dancing to get another drink you approach her.

"I think I work with your sister, Samantha at Google," you say and introduce yourself as John.

"Oh, you're her boss!" Claire says excitedly. She's had enough to drink she's pretty excitable in general.

You wonder what stories Samantha might have told her sister about you, especially if Claire heard about Samantha's recent rejection of your compliment about her ass.

"How'd you know I'm Samantha's sister?" Claire asks after you've chatted a little. You can see her friends watching the two of you, wondering if they should intervene and save their friend from the older guy she's talking to, but she waves them off subtlety.

"You have the same pretty brown eyes," you say. "And I've seen photos of the two of you on Insta. You do look very similar though."

"I wish I were as skinny as her," Claire says almost to herself and then adds, "but she's the pretty one!"

"Oh no, I wouldn't say that," you say as you put a hand on Claire's arm. She smiles and you suggest the two of you head to the dance floor.
