I'll go first! When I taught in New Zealand in 2013, I embarrassed myself — often — in front of my middle school students. As you probably know, American English is different than Kiwi English so in NZ cookies are biscuits, fries are chips, bathing suits are tugs, etc. I quickly learned (the horrifying way) that periods — the punctuation mark at the end of a sentence — went by a different name, too. Apparently, they're called full-stops... yet I was loudly reminding students to add mensuration cycles to the end of their complete sentences. You can imagine the uproar the quickly followed afterward (hah!) What funny work stories do you have? Let's have a laugh!
