I hated cubicles until I discovered open offices, then I just plainly hated offices:
hated water-cooler conversations,
hated the smell of reheated meals,
the unending birthdays of people I spoke to once a year,
the parties and outings that are secretly interviews,
the idle people that are always looking for killing time chatting,
the busy people looking for a nasty rumor to climb higher,
I hated commuting and hated having to stay longer just so everyone thinks I'm working hard,

But above all, I hated the middle managers that want to both be your friend, your boss and the person that will fire you to cover a fuck up.
