Interesting. Just for the freebie SI photo, I vaped with my horse, and she paid no attention to it at all. We went out in the pasture to take the pictures, and we interrupted her grazing, so she was focused on getting back to munching grass, so I guess she was too distracted to notice that I was vaping. I don't usually smoke or vape at the barn, so this was something she's not used to, but I guess she figures humans do all sorts of weird things a horse can't explain, and this was just another one.
Wouldn't you just love to hear a conversation among our animals and their companions or am I the only one with a bizzare enough imagination to think of something like that. "Let me tell you what my human did yester......." "Yeah well Penny's human...."
