Well am I?
TLDR: I imagine a bite or scratch from a fox would require a tetanus jab and I don't have time for that, covid restrictions aside.
Full Story:
I was out running this morning at 5:30 (yes, I probably am certifiable) and a fox crossed my path. He began to follow me, so I ran a little faster. He matched my pace, so I ran faster. 
By now I'm pretty much flying along, and this bloody fox is chasing me!
I'm panicking. I've only got five minutes left on my podcast, and I so want to finish it, because I'm on W9R3 of couch25k
But if he attacked me, I would need to have a tetanus jab for a fox bite/scratch, surely?
So I growled at him, and he stopped in his tracks and shot away in the opposite direction 
WIBU? Have I scared the poor fox for life?
Yes, obviously I've namechanged- I've been here donkeys years, and there's no way I'm going to be able to keep schtum in RL about being chased by a fox!! 
YABU- you cruel animal abuser
YANBU- he could give you rabies! and tetanus, and fleas, and follow you home and attack your children
