Isolation, and it's effects.

Don't call it Glad Wrap. It is cling film. Glad Wrap is a brand. In NZ. No one will understand what you're talking about.

Never address Ben's by their name. Anything is better. Sir, mister, excuse me. Heck, even "yo" is more likely to work. The same could be said for Tim. Avoid if possible.

Don't talk about beds, bread, milk or even yourself in third person (..Henna). It only leads to one place for everyone involved. Confusion.

It is always perfectly reasonable to be asked if you live near Hobbiton. It is entirely possible for NZ to be cold year round. We are all very likely to live on farms.

Phew, assimilation is hard.
