Sometimes intentionally, and it freaks my parents out that I talk like that to strangers’ kids.
Lol I did this at an amusement park once when some kids were breaking in line. Everyone was shocked and stood up straight. If my voice was a gun, I would have blown on it before I re-holstered it- it was that cool.
I do this all the time. My girls have cracked up at me for years. If a child is running in the store I tell them “walk”.. Of course in my “teacher” voice.
