I used to think ‘culture shock’ was just a term for being freaked out when visiting some place new or strange to you. Turns out it is a real ‘psychological’ thing. With an arc of behaviour,* etc. Reverse culture shock is real too, and one of it’s characteristics is a lack of common anchor points for conversation. Hence the returnee’s tendency to start conversations** that go something like “In Japan, blah blah blah.”
In Japan, woman of the teenage to young adult age seem to enjoy taking photos of the little treats they buy at cafes, etc., whether dinning by themselves or as a group.
Anyway, when in Rome…
* for lack of a more correct term
** generally conversations that no one except the returnee really cares to have – but hey, be patient, he / she has no idea in hell what you’re talking about either
