it's good that you got out- that's the best thing to do when feeling depressed, at least in my experience. i wish i could've been showing you NY yesterday, instead of feeling like someone was drilling through my sinuses, but alas, next weekend we shall conquer. ok, so you like borders, then i MUST take you to barnes and noble in manhattan- they are even bigger than borders and i'll take you to the one in lincoln center that i believe is the largest one in the city.
the coffee at cosi isn't the greatest. i'd recommend you try dunkin' donuts coffee or, gasp, starbucks. try starbucks especially if you like very strong coffee. aaaaaand, you can get it in the grocery store, so you can actually have it without setting foot in an actual starbucks. also, peet's coffee (sold a whole foods) and green mountain, which i believe you can find at any grocery store (it's also popular at gas stations for some reason) are supposed to be really good.

have fun at the museum today!
