Unfortunately it has gotten extremely common for students to mock me behind my back or to my face. I'm really not sure how to deal with it. Up to this point I have been ignoring it all, but it has really started to get to me and affecting me at work. I get mocked because I'm a very small woman with a "nerdy" voice. Apparently I have a very strong resemblance to Velma from Scooby Doo. When children mock me, they'll either call me Velma or impersonate my voice. I'm not sure how to exactly handle this situation, especially when they mock my voice, because they can easily say they didn't do anything wrong. So how can I manage getting personally insulted?
