To be clear, I’m not saying I picked up the pic’d stones and brought them back with me from our next closest galaxy . . .
But rather that I was holding them while recording the Andromedan transmissions. Well, I was holding two at a time—one in each hand—anyway. It turns out that holding any two (or more) in one hand produces enough clicking noises for sensitive microphones to ably record.
And yes, I learned this the hard way!
