I have to confess I first heard the "kitchen pass" phrase in the bar in a fighter squadron, i.e."hey PJ, is your kitchen pass good for long enough to have another beer?".
To be more politically correct, gender-neutral, and non-military, I should have said "My wife is an enthusiastic participant in my aikido journey, and wholeheartedly supports my goal of training 4 times a week." This is true, incidentally, but I still don't know how I managed it . . .except that she's awesome, and in my case, it's way better to be lucky than good!
