In my recent experience, there are several distinct culinary phases after ones' wife leaves for a several-days road trip with her Mom and Sis:
1. Friday - after work, bring home take-out catfish plates for self and son.
2. Spend Saturday working outside and simultaneously 'cleaning out the fridge' and snack cabinet... have 'friendly' competition with son to see who gets 'the good stuff' first. Eat peanut butter on Ritz crackers, and potted meat on saltines for the first time in a long while... hmmm, not too bad...
3. Sat. eve. - after son leaves to go jukin', eat chicken and wild rice soup, cold, straight from can... augment with beer, saltines, and vienna sausage as necessary. Then open every door and turn on every light in the house; including deck, porches and carport. Stream smooth Jazz radio off internet after turning house stereo system up to '7'... work towards organizing 'stuff' - open all drawers in filing cabinet, spread papers out on all available horizontal surfaces, drag junk out of closets, stay up too late - snacking prolifically as-necessary. Crash on top of made-up bed, lights and music still on.
4. Sun. a.m. - drink too much coffee, eat last of lemon pound cake wife left, while watching CBS Sunday Morning - then later eat brunch: tuna-in-spring-water (again, straight from can) with saltines. After another while - assess pantry, cabinets, and freezers; make grocery list so I can go buy some 'good stuff'.
5. Decide instead to ride golf cart buggy in the woods and on dirt roads.
Charging it's battery, filling a cooler, grabbing a .22 rifle, takin' off... see y'all later!
