I stay away from older ladies with blonde bob haircuts or very short or perhaps curly dyed psuedo red hair (not bright enough to be vibrant, sort of dark and browny, it's like they wanted to be edgy, but didn't want to go all the way.)

Those are very specific looks, but I've found 9/10 times it's predictive of someone who is going to snap at me about something I'll find mystifying. My shoes will be tied incorrectly, or I'll be a few minutes too early for an appointment, or maybe I'll have accidentally driven over the planter box they thought would be a good idea for the parking lot. (It wasn't! If there's one thing we don't need when trying to park a Mitsubishi Behemoth it's more random obstacles designed to fit neatly into blind spots!)

I'm not great with older women in roles of any kind of power in general. I tend to bring out the worst in them and vice versa. I find men safer and more predictable in general.
