We have a small kitchen, so we have a deal. When one of us is cooking, the other stays out unless we need help. I remember trying to cook a complex meal which needed perfect timing to get it right. My sister-in -law came in and started 'helping'. Then my wife came in to do the same. I kept telling them if they get the timing wrong, they will ruin the meal. I left and came upstairs and got on AB. When I was called to dinner, they had indeed botched it and the meal was awful.
