how it makes me feel:

i'm okay with it. dictionary.com has been fairly consistent this week. consistent, but not amazing. they're like the pizza place down the street from you that always has cheap slices ready. it's not the best pizza ever but they aren't the worst either and they're like right-the-hell-there. plus the dude kinda knows you because you always tip well and always in cash, even when you pay with your card so he tells you about his camping trip with his wife over the weekend even though you don't really care because you've never met her and don't want to but you listen anyway and nod and smile because you're not entirely dead inside, at least not yet. and the lady at the taco truck is nice and everything but you just don't feel the connection that you do to your closest pizza place and how many meals a day can you have that contain jalapenos before your insides just kind of surrender and scream "when-lord-when will i get vegetables that don't come from subway?" plus it's nice to have someone to say hello to even if it's just the dude at the pizza place because lets face it here people - no matter how alone we aren't, we're all still pretty damn alone. that kind of thing.

editorial note:

MW has kinda gone off their rocker this week. pukka? wtf?
