I want to grow up to be a Astronaut!

Isn't that what every kids wants to be? Or a doctor, teacher, cop, firefighter... any vocation that is easily described in one or two words and includes props or costumes.

Should I even care that my daughters will never pine to be actuaries, molecular biologists or CPA's. That I'll never find a Playmobile or Lego representation of what Daddy does for a living?
