how it makes me feel:

i actually like this one. i actually kind of like it a lot. it's weird. i didn't really have high expectations for the day. it's kind of grey here in seattle and it's getting to the point where the sun doesn't bother coming around until 8 or 8:30 if you're lucky and after seeing what MW was offering i thought the cosmos might just somehow be aligned to make today a fairly mediocre experience where nothing really goes wrong but nothing really goes right either. one of those cosmically neutral days where you neither generate positive or negative karma, leisurely riding a soft gentle stream of middling tolerability (yes i'm making up words). in other words it felt like a monday. luckily that feeling was fugacious.
