Yesterday In English Class...

I'm in accelerated english. It's more just a title than an actually hard class; no one in it has any difficulties with it whatsoever, so it can't be that hard.  Anywho, we were learning about whether or not it is she or her, he or him, who or whom, me or I (that one is easy), they or them, and whether or not it is possessive, objective, nominative.  My teacher started to give us a speech (oh yeah, I forgot that we or us was one too) about how if we didn't learn to speak correctly and differentiate naturally, then we students wouldn't succeed in the real world.  I just looked at her and thought honestly, how often does she mess up her grammar? Oh, wonderful English teacher who speaks "Picksburgese." Ha.  Hypocrites often bother me, especially because I'm generally set on the whole pronoun thing without needing to determine whether it is an indirect object or a direct object or object of a preposition and such.
