Well, Qatar is, obviously, not boring for everybody. It all depends on one's expectations,culture.
For me it is boring. Yes, I would like to go to parks, but I don't ,because the behaviour of many people there is not acceptable for me ,so I stay away.
I'd like to take walks, but walking along the Corniche breathing in car fumes is just not for me.
I love the beach...but I'd like to feel comfortable wearing beach attire that is acceptable to me...this is not quite possible here. Plus the beaches are dirty and not taken care of. so I go very, very seldom.
Just a few examples why Qatar is boring for me.
Now, I do not complain, as I knew very well what I was getting into before I came here.
This is just an explanation as to why I find it boring.
