Make a pot of coffee.
Drive to work.
Wait for an hour.
Hesitantly leave.
Realize there is nobody anywhere.
Drive out of town.
Realize there is nobody outside my town.
Turn on the TV.
Look at the news.
There is no news.
Drive down to the ocean.
Realize there's no horrible natural disaster present.
Drive to the gas station.
Fill up my car.
Blow up the gas station.
Some people just want to see the world burn.
lol...
^this.
Would everybody be gone or just dead? Because if just dead, I'm totally going to poke them with sticks.

You're weird.
I guess I would feel pretty down at first, but I'd like to think I would be logical enough to start gathering resources asap. Taking the gas from abandonded cars and saving it, looting whatever I think I'd need (generators for instance), getting acquainted with local livestock, trying to find sites with sufficient info on how to grow different things and how to butcher animals (since even though canned goods might last for a while, I will either run out of them or they will turn old in the end), loot the local hunting store for a lifes worth of ammo etc. And also, I would save whatever I'd find on the internet, because I might keep my computer going thanks to a generator but I doubt that every server in the world would run flawlessly for an eternity without being overlooked by someone.
Same here...
Survival training would kick in.
Since my well is drilled and has a submersed pump, and the power is going to eventually fail, I'd find someplace with a source of drinking water first.
Once water and shelter are secured, I'd hit as many hardware/hunting stores for all their 12 gauge #4, 00, 000 buckshot, and slug ammo, and .22 cal ammo too, for small game. And some .357 for my revolver.
Then I'd make a couple trips to all the area grocery stores, and fill my truck with as much non-perishable food as it could carry. And candles and matches. And bars of soap.
Water, food, and shelter.
Then, I'd occupy my self with the tasks of daily survival. Gathering fire wood, maintaining my shelter, preparing food... etc.
I liked Robert Duvall's line in "The Road", when Viggo Mortensen asked him what he would do if he were the last man alive...
"How would you know if you were the last man alive? I guess you'd just 'Be it'..."
Never knowing when the cannibals would come knocking, I'm sure I'd always sleep with my .357 under my pillow.
