1. The Head Rest
The casual head rest is a major sign we want to get closer to you. We are literally inviting you into our personal space by invading yours. We're not just brushing something off your jumper -- we are placing our face near your face. In terms of all (non-sexual) body parts in close proximity, the face is one of the most intimate -- you wouldn't want your face close to someone you didn't find attractive. According to Reddit user Xani, a woman will usually try this move at the movies, where she can "shimmy down" in her seat "and then casually lean [her] head on [your] shoulder." This will usually prompt the guy to "stretch to put [his] arm around her." Got a movie date in the diary in the near future? You know what to do.
