I don't know about the rest of you fellow expats around the world, do you still convert in your head the currency of your country back to the currency of your country of origin?
I don't. For one simple reason - because I have never really earned SEK. (I haven't had a job in Sweden since my last summerjob there in 1991!)
I have already started here, to just "compare prices with eachother", if you know what I mean? Thinking that "oh, the latte here is this much more expensive than the latte at the other café" or "the bananas were a lot cheaper at the other supermarket" etc etc.
It took me quite a while in the UK, to stop converting GBP back to DKK, and I still did it every now and then, even after four years.
Here, I convert the BND back to GBP (and them in their turn back to DKK sometimes too!), but I still have to keep the SEK exchange rate a little bit in the back of my mind as well, for every time I have to explain to a fellow Swede how much something is here... and don't even get me started on comparing prices on things with the family in Sydney or NZ...
Adding to this, we have all the trips Nathan is doing, where he finds interesting things to buy, in THB, YEN, MYR or SGD!
Can you keep up? Yeah, I know, it gets confusing...
