Two girls board a night bus in Bangkok, expertly and competitively bagging the upper-deck front seats. They’ve sent their men to stow the baggage. The Norwegian girl smiles affably at the English girl, realising they have the same intent: maximum comfort for the long journey ahead. Their bond is instant. The men get along too, but that’s immaterial. Twelve hours seems like two. A month of shared experiences follows, then flights between their respective countries. Wedding vows are witnessed, babies are born, families are entwined. Throughout it all the girls’ bond remains strong. This is travel friendship at its best.
