I like stories that leave you wanting more, leave you wondering, but don't tell you everything.
You can't really divorce yourself and your life from the world you live in.
When I heard Puerto Ricans in New York City, it sounded very strange. And the first time I heard someone from Spain, I thought they had a speech impediment!
Sometimes a scene works and acting is the easiest thing in the world and you don't have to do much of anything - just enjoy yourself and listen to the other actor. When it doesn't work, then every actor has different ways of dealing with the impasse. Sometimes you use memories from the past. Whatever. It depends from job to job.
