Horribly unAmerican-sized, borrowed coffee mugs:
Having no shoes but Havaianas to wear out in public (don't worry, I haven't lost my mind--packing no shoes was entirely deliberate wink-wink).
No laundry soap. After Googling "can you launder clothes with shampoo", I begged my reliable neighbor, who came through with the suds.
Blogging on an iPad.
Eating dumb food that I never wanted to eat in the first place, which is why it's still in the pantry. Stupid fad superfoods of gross dumbness.
