Advanced Dating/Ask her what she's wearing
From Create Your Own Story
"Hey, Sarah. What are you wearing?"
Sarah giggles over the phone. "Straight to the point, huh? I like that. Not much, at the moment. I could use something warm and cozy right about now..."
"I don't know about cozy, but I think I can help you," you respond. "Where are you?"
"In my dorm room (she gives you the number.) Alone. I'll be expecting you, David." *click.
Sarah hangs up before you can think of something clever to say. She's clearly been thinking about you more than you had realized.
