What about when you are walking home from the pub? What about if a mugger jumps out and threatens you and yours?
In the old days you could carry cane that concealed a handy sword for dispatching said blaggard in such a situation.
I have only suffered attempted mugging twice, once by two men with a knife who after my continued insistence I had nothing worth stealing on me which I did not gave up, this was pre mobile phone.
Another time a teenager approached me with a Rottweiler and said if I did not give him my money he would set his dog on me, I responded by petting his dog which was as soppy as shite. To which he started shouting don’t stroke my dog Before walking off swearing under his breath.
