Hi! This might be random to bring up but Miso soup is a bean paste, its very common here in Japan, but mainly as an acompaniment to something more substantial like oudon or nabe or something. It isn't really an acquired taste, it's nice the first time you make it, obviously that hippy dude wasn't showing her how to make it right.
Now i've got that out of the way, go you for being so heroic and hurling a desktop 0_o
I'd have thrown the macbook at most, so can you track this guy down or something? I mean what he was doing seemed pretty sinister.
