Toilet: A Near Miss

Moving across the world has been even way more of a change/shock for us then we had initially anticipated.
We knew that there were going to be new words for us to learn and that many cultural idioms weren't going to translate-
But we hadn't at all anticipated having to learn a completely new language. To a large degree that is the case here.
We constantly find ourselves saying words that people here don't understand, and conversely, we are hearing a whole language that we've never heard before...yet it's still English...just a different form of English...I guess...

Case in point: We took Halo and Ryder to experience a day in, what will be their classes, to help prepare them for school at the end of the summer.
They were both left in their classrooms while Raeleen and I sat in the lobby, just in case they became uncomfortable and wanted to leave.

Both of the kids did very well in their respective classes, however we found out afterwards that Ryder had a very near miss.

He suddenly found himself having to go pee while he was in play time, so he ran to his teacher and said "I have to go potty!!".
A potty in the UK is a learning toilet- the little ones that you bring on trips or leave in the kid's rooms while they are being potty/toilet trained. So naturally, his teacher says "I'm sorry Ryder, we don't have potties here".
Perplexed, and becoming desperate, he then started to repeat it frantically "I have to go potty, I have to go potty, I have to go potty!"
His teacher, nervous that he didn't know how to use a proper toilet, decided to race him to the toilet anyways, so he didn't have an accident.
Afterwards she told us what happened and let us know that she put him on a normal toilet and he went fine.
That didn't surprise us as he goes on a normal toilet all the time...then it dawned on us what had happened.
We explained to her that "going potty" in North America merely means going to "The Toilet", and then we all had a good laugh (and Raeleen and I a sigh of relief).
