I find a long silence is helpful. And look of disdain and disapproval.
I used to respond angrily, but realised it was a total waste of energy.
Now I give them my teacher face, say nothing and walk away.
However, the other day, I was incensed at a parishioner, who was extremely rude and interfering ( a habit of hers) in front of the new Parish Priest.
He had asked me to help with something and she reprimanded him saying, he shouldn't be asking me to do anything, due to my fragile health. The P.P was so embarrassed and apologetic. I very forcefully told her to mind her own business, that what I chose to do, was none of her business.
Parishioners, who witnessed it said I wasn't forceful enough!
Witzend, that is an excellent response.
