Stop in for a cup of coffee
Hence why I keep an emergency 30 pack in the Dart Cave for when I get little surprises like that. I can disappear out there until all the kids are in bed and then have the house to myself.
One year, my wife had the kid across the street over for an unannounced sleep over and she and my daughter got into a large bottle of perfume and broke it on the bathroom tile floor. The fumes in the house were unbearable so I spent the entire evening on the deck drinking beer and then slept in my car. I left them in the house with all the windows open.
