I worked at a high school doing IT. I kept student-returned laptops in a laptop cart. One day, to my absolute horror, baby cockroaches start crawling out of the cart, and infested my entire work area.
The cart was quarantined and treated by Terminix. After a while the cart was returned to me, and I had to sort through and clean/wipe all of them. I wish I could have just e-wasted the whole thing. Another round of hatching happened a few weeks later, from another laptop, but luckily I had put them in air-tight containers by then.
For me at least, it’s that I can’t do anything of substance until the scheduled thing is over. I can’t even start the video game while waiting because I’m worried I’ll get too engrossed and forget about the thing I have to go to later.
