If alchohol or some other mind alteration wasn't involved then you probably wouldn't have the question to begin with.

Once in a while I hit my sister back (we are both well into adulthood). She deserves it - she never knows when it's going to be and it's always the brotherly punch in the arm (not too hard but hard enough for her to recall it).

Wife saw it and laughed at her so it must have been okay - after all - she's the conscience.
