De acuerdo. I agree. My brethren there are just super SUPER nice and humble.
I am confused when to use "Es" versus "Esta" when describing what something is
Ser is for characteristics, place of origin, professions, permanent or semi-permanent traits etc. Estar is states of being that are usually transitory or temporary. ie. estoy enojado (I'm angry,) está casado (he/she is tried) están en la tienda (they are at the store.)
