This was a very interesting point of view, of course I don't know Anne so I wouldn't dare comment if it applies to her.

There is a similar type of syndrome for the foreign teachers, as well. I know, because I used to suffer from it myself.

The teacher feels angry against his/her own society, probably his/her own family as well and wants to leave behind everything bad he/she sees in the world he/she knows. The teacher gets the qualifications needed, goes on a vacation and quickly finds a place that is "different." He/she finds a job, meets some local people, makes friends and quite often forms an emotional relationship. Marriage often follows.

But then...

Once the initial cultural adaptation wears off, or the teacher finds him/herself settled into the new life, the eyes open and the teacher now sees that their new home has just as many problems, albeit different ones, that they wanted to escape.

Anyway, as noted above I went through a similar process, I have seen it happen to many many teachers, plus I have seen situations like the OP described among a few students here in Latin America, at the end of the day we all wake up to the fact that we are who we are, and if we want to change let's all try and change for the better.

(If you read this far, thank you.) Sorry for the long post ;)
