Qataris indeed are most people in the Gulf with extremely kind heart. Some may look rough, some drive crazily and many youngsters act irresponsibly (quite normal all over the world) but they’re unbelievably genuine, specially older people.

If you’re invited to their houses, they’ll fill you up with their generosity and hospitability even if they did not speak one word of your language and shared nothing with your culture. 

I'm happy you’ve experienced it first hand…:)
