Spanish teacher in 7th grade....She was an elderly woman who used to walk around with a thermos all the time which we all speculated was full of liquor. Some days she was an angry bitch, others she would just sit at her desk and smile.....I think we finally drove her nuts since she made no announcement she was retiring or whatever and just didn't return the next year.
Oh shit, and then there was the ISS "teacher"......About 3 years after I graduated, my mom got me a job as a lunacy officer......Meaning I guarded the locked room at the hospital for patients being transported to Sand Hill. One day I showed up and they told me who was in there....She looked so broken, but they said it was related to her husband....Not her job.
