Thats where routine is so important. Yet we all know things happen that pull us from that routine. So far I deal with the inside stuff and hubby does the outside stuff. I drive, so he stays outside until I clear the campsite then enters the coach. But we still ask each other questions "did you do this? was that done? The usual answer is "yes dear I did" It's a joke, but we both understand how easy it is to forget something.
Our last weekend adventure I asked if hubby packed the Scotch and toothbrushes? His response was "which is more important?" After a brief discussion we both decided the Scotch.
Life is short laugh, learn and move on.
