Let's say you are a guy, and you're talking to a girl/woman that you just recently met. You're talking about paint colors and the paint colors of interest seem to all be on the sweater you're wearing. This person is using their hands/fingers, touching, kind of rubbing the arm of your sweater to explain. Is there anything being said besides the literal part of this? Would you be comfortable with this, or is this getting into your space a little too much?
