I often dowse when shopping. One day at the supermarket I was using my pendulum over the avocado display to determine the ideal one for my needs. (I used to dowse asking for the best but then I often wouldn’t eat it when I’d planned, so by the time I did it would be past its best. By fine tuning it to ‘ideal’ things work out perfectly.)
One day there was an elderly lady watching me. She came over and, instead of asking what I was doing, she asked what the green thing was and if they were safe to eat. I said that yes avocados are not only safe but delicious. Well, she floored me by replying that her daughter-in-law had tried to give her some and she’d wondered if she’d been trying to poison her. Motto, best not to jump to conclusions too quickly!
