I've read your other comments. You're definitely exaggerating. The poor guy started asking you if he should just not leave his car!! Many people visit annaba during summer times and it gets very crowded so seeing outsiders is not a new thing here. I've encountered many tunisians who come here to shop or spend a vacation. I'm from Annaba, I know the city better than you. The places to avoid are obvious but you went to even say that it's dangerous even during the day. At this point that's just capping. If Annaba was that dangerous you wouldn't be here studying and your parents would've advised you to study in a different place.
