I have a force field that lets me know when intruders are near
I can lean away from someone trying to touch my hair so fast and look so crabby that so far no one I didn't want to has done it. I'm sure my day will come though.
Now don't let me be all having a nice curly hair day and have one of my chihuahuas with me. Why do people think if they stop and talk to you that it's ok to pet your dog? Chis aren't known for liking strangers and they look all offended that I have taught my dog to not like strangers. Oy! It's not public property!
