So we were running errands today and I had to go change the boy. I took him into the bathroom and had him down on the table. He wasn't having it and, of course, was screaming his little head off. Well, about the time I'm doing that, this kid who's about four or five prances up and is like, "A baby! Hi baby!" and stands there next to the changing station. I don't really care, just a curious kid, he can hang out. Niko's still screaming, though, and the kid kept going, "Baby, baby, baby!" Not loudly, and at first I thought it might even be repetitive enough to calm him down a smidge. His Dad comes around the corner and sees him. Tells him, "Leave them alone bud, they're busy," and starts using the urinal. I haven't said a word this whole time, just focusing on the task at hand. Then I see this kid's hand come up over Niko's mouth and I just reacted. I reached out and took hold of the kid's forearm really firmly. Not squeezing, not twisting, but he wasn't about to get out of that grip. Was a bit surprised at how fast I moved, to be honest. And I just looked at him. He looked terrified, and I remember just feeling this sense of pure fury. At this point the Dad looks over his shoulder and sees me. I didn't even have a chance to explain myself, he just looked down at his kid and said, "See what happens when you don't listen?" He zipped up, apologized for him, and hauled him out of there. I guess I'm just thankful I didn't have my ass painted all over the bathroom walls, because if the situation was reversed, I can't imagine not being totally pissed.
