He made his move.  I made mine.  Mine was towards the pile of garments a few feet to my right.  His move was towards me.  I had the crucial decision whether to put on my briefs or grab the essentials before I was grabbed.  He moved fast for a man who seemed to relax on life support and got hold of my arm.  Was I about to enter a sparring match with this old coot?  And if so, is it billable time?
