Best to walk away backwards so as to keep an aye on your assailant.
I was out on a football tea trip up the tyne on the beer boat, when we docked at about midnight this one lad decides to urinate not 5 feet from me my mrs my broth in law and his mrs. I politely asked him to take it elsewhere to which he replied , she didnt complain last night.
Now I gave the lad 4 chances to apologise , but he kept repeating it , so I lamped him - just once , However im 6 foot 3, 18 stone at the time, 2nd dan at wado ryu and 10 years a boxer. His head hit the road before his body and he was completely unconcious. He ended up in hospital with a fractured skull I ended up getting done for assault but I was more scared id killed the feller.
Worst few weeks of my life praying for him to pull through. I now keep well away from trouble and cross the road to keep away from potential trouble makers its not worth it.
