Hummmmm.......never know what may be going through their minds, but try not to place too much emphasis on what he did. Do you think he knew the lady who was riding in the car with you? Maybe he was trying to see who she was. I would think he was being more nosey than anything else, but the fact you have not seen him in that length of time is very good b/c the longer he goes without actually seeing you.....the more interesting it may become when he does lay eyes on you. So, how did you react? Did you wave or anything? I hope you looked really so great it hurt his eyes! (lol)
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!
