Random but is your Narc very sensitive to slight temperature changes and cranks up heater or air regardless of what others feel (or regardless of bill?)

He’ll ask me if I’m cold and start shivering when the temperature is moderately cool and seems to expect me to agree with him. When I disagree, he pouts and goes silent until I say go ahead and turn on the heater. Then he’ll put it on FULL blast. The same situation will happen when it’s slightly warm and he’ll put on the cooler, yet he complains constantly about how high the electricity bill is and how much other family members use the thermostat. Just a random thing I noticed about him. I’m pretty convinced he’s a vulnerable (covert) narcissist.
