So far, very well - sticks perfectly, no movement. But let us see the evolution.
Concerning Turkey, thanks for sharing concern, but there is no nervousness from my side. I work in Paris, commute daily with RER B and C lines where bombings took place, visit boulevard Beaumarchais because of the many photo outlets, used Brussels airport shortly after the bombing, went to Tokyo one month after Fukushima blew up (at a time where the Lille orchestra refused to get there), etc.
I have colleagues who lost friends or relatives in Moscow airport (bombing), Brussels metro (ditto), Paris Bataclan (shootout).
I may call myself lucky, but honestly, the majority is lucky here, no comparison with Bagdad or Mossoul. My grandparents experienced two real wars (not to mention independence wars in Vietnam and Algeria) ; I only have to deal with that rampant one. Again, no comparison.
My travelling to Instanbul will not significantly change the odds of falling victim to whatever. I go there to meet good colleagues from Turkish railways, reason enough to share a bit of their daily living and working conditions. When I went to Tokyo after Fukushima, staying about one week, the equation was clear : why should I avoid a one week stay when thirty million people, for all sorts of reasons, will stay there for their entire lives ? same with the earthquake etc. risks. Sure these are serious threats (much more so than the bombings, I guess), but again, why should I refuse to visit people and turn down an invitation on the grounds of irrational fears when themselves are hundreds of times more exposed ? What if my Turkish colleagues would say "nah, we're not coming to Paris, too dangerous a city, and we don't trust the police by the way"? I'd find that very strange, so I guess I'd hurt some feelings if I chickened out.
