By far the coolest and, more importantly, most caring teacher in the history of the universe. Her student-advocate award next to her bookshelf says it all. One might say she may even be “too caring”. However, those people are obviously stupid. MC is the type of teacher you can talk to when your grade isn’t looking too good and the type of teacher you can talk to when your life isn’t looking too good. MC is the type of teacher that literally always has your back, even when you crush cheez-itz in her clean chrome books. MC is the type of teacher you can call your friend without looking like a complete frickin loser. MC is the type of teacher to act like she gets irritated then get called out for faking it. MC is the type of teacher that is hands down, truly the best teacher in the history of the world.
