Translation of Installateur

Writing autobiography in another language has some advantanges. You do not have to think to much about the story and you can concentrate on the foreign language. Spanish is very suitable for that.
Once they see a foreign person, their primitive thoughts come up and they start to hate and dislike without any actual reason. Whose fault is this hate? Is the fault of the ones who are afraid.
We were Lao Cai around six o'clock but the train left only at eight. I was somehow relieved though that we had all the dangerous bus journeys behind us and that we left this lovely place soon.
