Ok, please be kind, I'm not very good at Haikus.

But here's my attempt.
On my new galaxy tab,
oh you want me to teach?
let me click this mouse and you speak.
Angry today, husband cheating,
I yell at students
though they ain't bad.
anger out, feel better now,
students quiet,
I go back to emailing.
Okay, I teach,
you do listen and repeat
Otherwise don't speak.
Hate these kids, why don't you?
They make me work, don't want to.
Let's be friends over soju.
VP says no school,
you stay home, but sign here
because you must pay with vacay.
You teach 5th grade today.
What? no. No lesson plan.
Class start in 1 minute, go.
