Hello Teacher!
So, some of my students greet me with a "Hello Teacher"...i'm not sure why, maybe they feel strange using first names or maybe they just don't bother to learn our names, but anyhow so one of my students, is always particularily smiley and happy as he greets me with a bouncy, "Hello Teacher!" so, i have taken to responding, "Hello Student!"...A couple of days later, i walk into class and he is wisely telling another student, "She doesn't like being called teacher, she likes to be called Christie"...point taken i guess! :)
