Thanks for your reply and question.
It is really not about trusting each person or getting to know them as close friends (monkeysphere), but just being gracious and courteous to everyone, even those who we do not believe are providing a welcome interruption to our day. That is the challenge of course, but it is our choice.
Blessings!
Then we're talking about maintaining a persona (the right persona) despite everything. Firmness and clarity are vital with this, obviously. However, still: how do you have enough energy to carry it through, always ?
No one has enough "energy" on their own. This is where the power of the Holy Spirit is truly required.
Have a blessed day with much wisdom and clarity!
