Sofia×Nukuʻalofa
Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Sofia uses the BGN (лв) and Nukuʻalofa uses the TOP (T$). Language shifts too — Bulgarian in Sofia, English in Nukuʻalofa. Be careful behind the wheel: Sofia drives on the right, Nukuʻalofa on the left.
