genevieve: you're a very nice lady. are you a lady? or are you a girl?
me: i'm in between.
genevieve: oh, you're in between. well, you're a very nice lady and girl, and a very nice in between. you're a very nice in between. [waving at the woman across the table from her] do you know her? she's a very nice in between.
