You just need to listen. Had a guy I was talking to online (networking for my work) that I started casually chatting with. He was always dropping hints about drinks but it was never going to happen because he's not remotely my type and I don't do "drinks".
Today in casual conversation he just happens to drop that he "used to be" a skinhead.
You should have seen how fast and hard my eyebrows hit the ceiling. Boi bai.
