Chuck is terrible about coming when called, and the whole calm-assertive thing does not work with this command. If I don’t dig down deep inside my throat and scream his name like an ogre who is about to sever his head with a rusty axe, he will completely ignore me, and even then I sometimes have to follow his name with a hearty, menacing, “GRRRRRRR!” Doesn’t make me look crazy at all, just standing there in the middle of an open field screaming like a troll at nothing.
