self defense

LOL, a 'little' Aikido move would be the most basic hand disengagement, and it may have saved me some trouble back in college. It was nonviolent, but it showed the two drunk kids that I knew something. And then a cop conveniently walked around the corner. All was well. Lucky.
Looking for a new school. I'm picky. It's been 10 years.

And I agree. Physical confrontation is a last, last resort. Confidence saves a lot of trouble.
Don't forget to have a quick look at your car upon returning. Glance under it while at a distance away (so you don't look obvious, and are in a better position if someone is under it) and the backseat before you get in. Just be aware, aware, aware. No fumbling for keys or phone or tools.

I want to add to the meet their eyes part I said earlier. It's a glance, but a direct one that just says 'I see you.' Nothing more, because then you verge on looking threatening. For animals and people, a stare is a threat of harm, and might trigger a response rather than avoid it.
