Not sure there was a topic about this (probably yes but could not find it). When we (waiguo ren) go back to our country, sometimes we need a day or two to get used to it again.
Nothing big as far as I am concerned, but I noticed for instance that everytime a pedestrian light is red, I stop and wait while the big majority (even mums with children) will cross the road if there is no car.
Also another thing, I remember many waiguo ren saying they were sick of taiwanese giving them a look (pretty much everywhere in Taiwan), but I noticed it happens much more often in my country (France), especially last time when I went to a library to study chinese for an hour, every single student look up from their book to look at you It has actually always been like this, but I must say I totally forgot about it! And this made my mind change a bit about Taiwanese giving you looks, or maybe they do it in a more subtle way.
The food is so different. Being a vegetarian, I can't believe the difference in texture and taste of tofu here, made in France or Germany (and it has twice the protein it has in Taiwan).
Anyway you get used (back) to it after 2 or 3 days but it always amuses me.
Share your thoughts please.
