It must be the season.
Two non-interns have recently told me that co-workers have asked them whether they were interns.
Both have several years of experience. One was actually reporting to work as an editor.
So, if you see new people in the newsroom this summer, and even if they look kind of young, say, "Hi, are you new here? My name is ..."
And if the new person happens to BE an intern? Treat them well.
