It is not a good idea to mess with little old ladies!
My SOs grandma got up evry morning a 4 to start her house cleaning. She went on the back porch for her mop, and there was a guy out there, with a screwdriver or something, raised to stab her. She backed up, grabbed a claw hammer, charged the guy, grabbed him by the hair, and beat him with the hammer until the hair she was holding came out, then she kicked him in the privates and chased him out of the yard. When the cops got there she told them he was lucky she did not backup the other way, where the butcher knives were hanging. That will teach him to mess with a poor, defenseless old woman!
