I think, "I'll just do this one last thing and then I'll go inside." And there's no need to put my gloves on because I'm only going to do this "one last thing." Then, before you know it, I'm pruning just one more thing, and still no gloves because I was just going to be outside another minute or two and then go inside. I didn't realize I'd caught a thorn, or that it had caught me, until I looked down to see why my finger was stinging. Yes, that's blood. That thorn was about 3/8" long!
