[Boiling water on the stove, how quaint. But Reo really isn't judging! Maybe this word doesn't have electric kettles, or maybe this person just doesn't own one, and they have been welcoming enough to let him in.]

..Do electric kettles exist here? Not that I'm complaining! I just want to know if they do, so I can buy one for myself.

And black tea sounds great! [If there was ever a time for caffeine, it would be a day like today!] Thanks!

[Should he sit down? It feels kind of awkward to stand here and literally watch water boil, but at the same time taking a seat kind of implies you are staying a while and he hasn't been invited to! So Reo will simply stand in the kitchen and hover around the door way, so not to impede too much on Eren's space.]

I need to exchange my Yen for whatever the currency is here. I found the banking app on this phone [Reo even pulls it out of his pocket in demonstration] but it's useless! I can't log into any of apps from home. I figured I can at least take what cash I have to an exchange until I figure out how to access them.

[easy peasy. Right?]
