I do not agree with Kamenko and Dragana, here are some reasons:

When it comes to Sarajevo people they are very open mind, and they like to talk about Sarajevo, ant its diversity. They are so proud of the fact that "Sarajevo has 4 religions, 3 official languages and that is European Jerusalem".They are all familiar with those cultural differences, and they like to share it. 

Also, they like to talk about politics as well. Favors topic is complaining about government "that they are not doing anything, everything is the same and nothing is going to be changed". 

When it is coming to "war topic", it is something where you could be sensitive, because some of those people lost their relatives and friends, and if they want to talk about that is fine. But in general, at institutions like museums, libraries, schools, galleries.. they are very open to talk about it and I felt very free to ask what ever was my interest.
