Future occupation (or occupation with the future)

Colsen still pretty much daily brings up the topic of what he will do when he grows up.  The list of occupations continues to grow and his dreams grow wider and wider.

Miles rarely participates in these conversations, but we recently had this interchange:

Miles:  Finally! I know a job I can do when I grow up!

Me:  What do you mean?  There are lots of jobs you could do.  I could see you being a doctor or a teacher or a missionary – oooh, or how about a pastor?  I could see you doing that.

Miles:  Nope.  I’m gonna be a cockroach-scarer.
