The amount of massive excel sheets I've seen in various departments, when I was working as an office IT was ridiculous.

Mysteriously appearing mosquito bites, even if there seems to be no mosquitoes around.

That's in Taiwan. They have fruit fly looking mfs, which make no sound and are almost invisible, however their bites are as painful as mosquitos. Pain kicks in after some time, so you can almost never tell.

These insects are called Forcipomyia taiwana.

Oh it's the same in Taiwan!

Also, to stop, you need to press the stop button in the bus. In my country (Lithuania) all buses had these stop buttons, but they were never used. Took me a bit to understand, that people actually use them here.

Oh don't worry, you're not alone. Me and my wife were convinced we had bed bugs first 3 months living here. Now you'll know what to prepare for next time!
