Well, don't feel too badly. I was usually the same way unless I got a creepy feeling about somebody. Then a guy I had known almost all my life said something about a girl at work who seem to be very forward or flirty. I was shocked b/c I simply saw her as friendly. When I told him that I was as friendly as she was.....he said, "Yeah, but you've known me all my life". I was so surprised that I wasn't sure how I was suppose to act anymore..... After that, I reframed from appearing to be "overly" friendly! (lol) But I wouldn't think what you were doing was in any way a flirtatious act. Like I said.....it takes all kinds to make up the world!
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
