Ghost attacks and rude guests

I’m not the one with leash aggression, that’s Mom! Mom is the one that growls and snarls and gets all exasperated every time I stop to sniff something in detail and the sudden braking whips her around. She’s the one that throws a temper tantrum and barks bloody murder when we chase a squirrel or a cat. I don’t know why she can’t just chill, so I usually ignore her while she’s acting out and being unpleasant.
