Younger woman Sign of Interest?

[2Rocky]

Met her at a pub run for the first time Wed Night. She was there with her parents. She's 20 years younger than I. Back in town after grad school.
Talked and vibed, didn't exchange numbers, and left with a handshake.
Wake up the next morning and she has sent me a friend request on facebook and is following me on Instagram. Is this the new "Call Me maybe" of this Decade or what?

Or just the new social currency?

Is this the new Call Me?

I think you mean "text me," since young people don't call, but yes. Get her number and text her.
