Friend of RD: “Is RD bossy around you, too”
RD’s love interest (LI) at the time: “Only in the bedroom.”

RD to friend: “It’s hot, do you have an extra rubber band so I can put my hair back?”
LI to friend: “Yeah, her hair always gets in the way when she’s doing important things.”

At a nice restaurant, seated at a table with close friends and family members:
RD to LI: “I’m full, do you want the rest of my dessert?”
LI: “Sure. I ate the rest of your dinner. I’m eating the rest of your dessert. What am I going to eat next?”

Objection to LI: I can't be your friend with benefits.
LI: Can you be my benefits without friend.
