Kim,
Do a self defence class - I have been practising Martial Arts for over 25 years, and it becomes second nature - which is what you want.

I think if you keep your distance, and he is keeping his, things will work both ways.

AND

If you do have a PT gathering, invite Gini (and she can invite all the firemen she knows!!!) and Phred (who can do the same)

Hehehehehe

Take care
M
