I'm in the process of getting my teaching credential to become a high school teacher. I've been doing volunteer work with middle/high school students in the meantime to gain experience. I've grown up in a very Southern family and have a rather old-fashioned habit of using terms of endearment when taking to people younger than me (I'm 25) -- things like, "Thanks for helping me clean up, sweetie." None of the kids have ever commented on it, but recently my coworker suggested that I stop, saying that it sounded patronizing and that I "wasn't a kindergarten teacher." What is your take on this?
