There's a little exercise I use when someone is bugging me ... try this & you won't need tFS to hide anyone from you
[I stole this from a book--some of you will probably be able to figure out which one ...]
So I picture myself in water, and the other person throwing something nasty at me (which is what a lot of people do with their words ...). Then I picture myself becoming as clear and transparent as the water, and the nasty thing passing right through me.
At first when you picture this, you'll feel resistance. What you're going for is, you don't fight it, you just let it pass on through.
Do this, and people will not be able to annoy you the way they did before. The power is all yours, to be or not be annoyed
