How to Sign "Interest"
To sign 'interest,' start with both hands open in front of you, placing your dominant hand near your face and your non-dominant hand lower near your chest. Move both hands forward away from your body at the same time. As they move forward, bring your fingers and thumbs together so both hands close into 'flat O' or 'A' handshapes. The movement should be smooth, as if your attention is being drawn toward something.
