Is it always true, sometimes true, or never true that a regular quadrilateral have 2 or more obtuse exterior angles?

I can construct a quadrilateral with interior angles of 91,91,91, and 87
giving me one obtuse exterior angle.
I can construct a quadrilateral with interior angles of 89,89,89, and 93
giving me three obtuse exterior angles.
What do you think? 
I see that it would be always true if I understand correctly

but ...
I gave you an example where there was only ONE obtuse exterior angle. 
we have problem it'sa regular quadilateral example given by u is not correct
