girls of reddit, what is the most obvious sign you gave to a guy and he didnt get it?

I'm a guy and here's the most obvious sign I've missed. I hate this story...

I'm a sophomore in college and I'm back in my hometown for the summer. Randomly run into this girl from my high school that I always had a crush on. We talk about what we've been doing since college and so on, and exchange numbers.

Later, she texts me to say that she's house-sitting in this massive house, and she thinks I should come over for a super fancy night in a super fancy house, eating crackers and drinking wine. Just the two of us. So I go. Obviously, I go.

At the house, we're sitting real close on a couch drinking wine and talking. I forget the exact words, but at some point I ask her, "Do you like kissing?"

She smirks and says, "Well... not talking about it..."

I said okay, then I talked about something else and went home an hour later after an uneventful evening.
