The scenario of these two teachers getting into it over a pupil is virtually impossible HOWEVER, I've seen older teachers get pretty catty over whose flirting with the new, single (usually young) male teacher. Kind of like they can't decide if they want to mother him or screw him -- or both. Also, remarks made at the local pub about how one dresses or conducts her class can't get danders to rise. I'd love to have these two occupy classrooms adjacent to mine and watch the tension mount throughout the year. Maybe fan the flames a little at the local pub one Friday afternoon, then suggest they meet to settle things on a Saturday, not in their classrooms, but in the school's wrestling room -- big mat, padded walls. Of course, Mr. Bear, being a person of high integrity, would serve as the referee. Also, he has keys to the mat room.
Who would win? Hard to say. The brunette must be a physics teachers, because she has Einstein's equation of relativity on her chalkboard (LMAO), and the redhead looks like the stereotypical English teacher. Besides, as the self-appointed ref, I can't take sides.
