I react in various ways, just depending on my mood. Over the years, I have employed all sorts of strategies with both extremes. A couple bad meltdowns that had the neighbors scared of me. And some calm and rational discussions (not many of those). That was in the days when I still cared about what the bible said.
And I have been on various Do Not Call lists. Both respected and ignored at times.
My slam dunk, though, happened at memorial time one year. I arrived home to find a Jesus tract in my door and a JW lady just getting in her vehicle. 3 other women in her SUV.
I walked over to the driver's side and when the lady rolled down her window, I sort of leaned in so I could see all of them.
I asked them, "Do you believe in Jesus?"
"Oh yes...of course we do!"
"Do you believe he shed his blood so the whole world would have a chance to be saved?"
"Of course!"
"Well...if Jesus gave his blood so we all could live, why don't you give blood? So other people can live? Don't you follow Jesus?"
They were stammering and trying to find a bible verse when I walked away. The one lady was shouting something about Sacred!!
That's the one I would use again if I couldn't think of anything else. Just for an opening maybe. And if I was in the mood, I would invite them in. Then we could talk about blood. I would make tea.
