Lost and Found basically sums up my own view on this.

With this question, I don't know if you are hinting at something like this vibrational attunement method that seems to have generated a bit of interest on this site for the past few days.

If you are, I ought to point out that trying to control external conditions (like other people) is a slippery slope to an unhappy life.

Yes, I know I mentioned previously that I use that method to move slow drivers out of the way on freeways but that's really just me having a sloppy vibration about those sorts of people. The better approach would be to clean up that vibration about "slow drivers in the fast lane" so I don't encounter them at all. But, at some level, I guess I find it kind of fun to be faced with this sort of experience and then deal with it in that fashion.

In addition to what Lost and Found has said, I would like to point out that if anyone is behaving in your reality in a way that is not pleasing to you then there must be something in your vibration that is attracting it...otherwise they could not be there.

This can be hard to hear sometimes because it really can feel like someone else is causing you to have a reaction to them but it's actually your observation of their behavior that is causing a reaction within you, not the behavior itself.

So the best solution is to "clean up" how you feel about them and if they have a part of themselves that is a vibrational match to your improved feeling about them, you will only subsequently encounter that in your reality.

If they cannot match your improved feeling, they will clatter out of your reality

...so, either way, you won't get the cold shoulder any more :)
