I confess I don't know what to do when I hit a woman unintentionally.
What I mean is this: I get up and she gets up and we both hit our heads together. Or for instance I am throwing a frisbee, it turns and she get's hit in the face, or breast or legs or whereever and bleeds.
I found "I am sorry" to be overheard on a regular basis. Be it that I know the woman or not.
Or a soft version of it, touching her fresh clothes with my shoes to create a big spot. I found things like this ruin dates for me.
So how do you deal with it - be it that you are on a date or not and she's just a random woman who happened to be there at the wrong time.
