New answer.

I watched "Angels with dirty faces" (1938) today and I got my new answer to what I'm going to say when people ask me what I do in Berlin by Rocky Sullivan.

Example conversation:

- So what do you do in Berlin?

- Just sittin' around lookin' pretty, dance a little, play a little, (kind of a hostess).

Isn't that just a great answer then saying nothing?

I liked the movie. To little Bogart(yes, if he's not the main character it's not enough for me), but great none the less.
