So it's typically OK to describe people you're related to like "my friend," "my roommate," "my S.O.," etc. Why do people give me strange looks when I describe my friends more ... well, descriptively -- but still call them "my [whatever]?" For instance, if I tell my friends who are in their first year of college to join me at the dinner table, "I invited my freshmen over to eat." Does that warrant snarky remarks, like "Oh, so they're your freshmen, now," or would you say something like that yourself? ETA: Why is it indeed OK to say "my friends," then, as a possessive kind of phrasing?
What kinds of things do you typically say that get you weird looks?
