Haha, that's interesting! I would think that group would be the hardest as well. I hope it gets a bit easier. At least you should be able to face that fear easier over time!
I get anxious/uncomfortable when I have to make them pay attention and actually do their work. Some of them just want to be on youtube the whole time or try to quit early to use the computer and I have to be the grown up to get them to pay attention. I tend to be a passive person, so this is definitely the hardest part for me!
If I wasn't used to it thanks to Korea, it would also make me nervous when they're just talking to each other in Somali and I can't understand anything. But I'm ok with it since I've gotten used to it
--I can also usually tell if they're talking about me vs. something else, so that helps too.
I hope you had a nice Christmas!
