Okay, etv78, here’s some advice: you really, REALLY need to start developing a much thicker skin, especially if you plan on being a teacher. Kids can be nasty little shits, and if you get this hurt by a freaking message board, you’ll never make it through the first day.
I mean, good luck and all, but you seriously need to work on your issues with taking criticism. Even if you have to fake it til you make it.
