The first day or week wouldn't be so bad for me because, as you know, I'm a tin foil hatter, I'm equipped to go for 3 months w/out power . . . yup, I have the propane tanks, the non perishable foods, water, .45ACP, a bajillion batteries for various high intensity led flashlights and radios etc etc.
It's really is amazing the things and people we take for granted on a day to day basis, ''loved ones'' in particular, when you see certain people that are important to you in your everyday life, you might as well almost hate them at times, but when they pass away or go away for good for whatever reason, that's when we get our asses kicked. . . the human condition I guess.
Sometimes it's a good exercise to just sit still and quietly, maybe contemplate the stars . . whatever, but just think about everything, this is how I would spend my first few hours.
