And while I'm rambling on incoherently when I should be getting lunch:
We've somehow managed to cause the mosquitoes in our place to mutate.
One of lzh's more serious problems is that she's a mosquito magnet. Seriously, if you ever need mosquitoes, just stand near lzh, you'll get plenty of them. This means that over the warmer, mosquito-friendlier months, much 蚊子香 (mosquito-repelling incense) is burnt.
The result? We're more likely to see mosquitoes flying around our apartment in the daytime.
