I'm an intern at a social services non-profit. My boss, being a non-native English speaker, asked me to edit some of his papers for grammar. They're for a class that he's taking and concern social services, but not the particular organization I'm working for.
I was glad to do it, since I felt as if I wasn't being particularly useful otherwise, but I'm not sure if it was appropriate for him to ask, since as far as I know, it wasn't related to the organization.
