One step at the time

Being a beginner foreigner is quite a challenge even for an accomplished traveler, nevermind the Citizen by Default. The list of Things To Deal With isn't that long really, just a tad overwhelming. Here it comes:

1. They're doing everything arseways here (meaning not the way you're used to; that being Wrong by Default)
2. You're not at home

Simple.
Threeandsomething years, one Ultimate Other Half, three addresses, one dog and one baby later the list has changed somewhat. Now it is good for both New Home Ground AND Old Home Ground and it goes like that:

1. They're doing everything arseways here/there
2. You're a bit confused where the home is

Alas, you have become a Foreigner by Default. Congratulations, you may collect your prize at the Passport Control.
Anybody else got an inkling that the problem might be me?
