In reasons I should've shoveled the walk when I got up

Not only would it have been easier three hours ago, before so many people walked on it, while, "I'm sorry, but I don't have a job either and can't afford to pay someone to do something I can do perfectly well myself," is a pretty good reason for not paying someone to shovel the walk, I think I like "It's done already" better. I don't need to actually give that excuse to the nice young man who shows up at the door, it just exists.

In my defense, it was still snowing until close to an hour ago.
