I'm glad Meagan was fine - geez kids can be a worry!
You could offer a course as simply a Self-Defense course. Many moons ago I took such a course at high school, and am glad I did. It gave simple, effective ways of disabling and/or putting the attacker off so you could run and get help, and the course also gave tips as to what situations to avoid to keep yourself safe/r.
Simple things like thumbs to the eyeballs, stomping a high heel onto toes or kicking the shin (and obvious other spots), carrying your keys with you when returning to your car with a key wedged between your forefinger and middle finger - so you could hit the atacker in the breastbone where it really really hurts (try it - gently - it really works. I still do it to this day, 30 years later,(carry my keys that way - not stickiing my key in my breastbone
, at any hour of the day). If someone is trying to choke you - get some fingers under their hands so you can breathe long enough to stay conscious and get away. Or grab their pinky finger and snap it back hard and fast. Instead of yelling "Rape" or "Help", yell "FIRE" - it gets more attention (sad as that may be).
Those sort of things. Keeping a heads up attitude for trouble. Let others know where you will be and when you expect to return. If you can, keep a cell phone on you.
Yeah it does sound gruesome, but if someone wants to hurt you- they deserve what they get. If more people knew how to react quickly in an emergency to save themselves, it'd be a great opportunity to save people injury, or worse. Don't worry about fighting fair - fighting dirty can save your life.
