Chemistry needs math

I chapter

,,For fucks sake’’
September 1, one of the worst times of the year, and it for sure is not the greatest for Lilia. She’s a math teacher at Mihail Kogalniceanu high school, she has been teaching in hell for 30 years and despite it being draining she still likes her job of torturing children. Her husband has been married to her for over 15 years, and only now has he realized the fact that he’s gay, he falled for a guy at his work place and leaved Lilia for him. Lilia makes her morning coffee and posts a motivational quote on facebook. The truth is that she hates her colleagues . 
,,Fuck I’m late’’
She gets in the car and hurries to work. At the first traffic light she sees a red car kissing her car. 
,,What the fuck, are you even looking when driving’’  Lilia asks the person in the red car.
,,It was green you imbecile’’ said the woman angrily.
Despite Lilia being angry at the unwanted accident, the first thought that came in her mind at the view of the other lady was ,,she’s fine’’
,, Are you sure you’re not damn blind, it was red’’  yelled Lilia in response to the offensive words, whilst still gazing at her looks.
 Lilia looked at the time and was startled at how  late for the school opening she was gonna be if she wouldn’t hurry, the lady was about to say something in return but Lilia interrupted her:
 ,, You know what I don’t have time for you, I’m late for work’’ 
She got in her car and drove as fast as she could to get there on time. To her amazement she wasn’t that late. After the opening, all teachers had to meet in the principal's office as in any other school year. The principal said she had announcements for them.
,, Thank you dear colleagues for being able to come here on the start of the new semester," said the principal calmly.
,,As you know some teachers such as mrs. Ana and mr. Marcel ,have retired last year, the school found a new chemistry teacher, welcome Mrs. Violeta Cebotari’’ said the principal happily.
,,Oh shit’’ said Lilia in disbelief under her breath after seeing the new colleague's face.
,, Good morning, I’m looking forward to working with all of you ’’ said Violeta before sitting down a few chairs away from her, whilst giving an unfriendly look towards the surprised woman. 
,,This day couldn’t have gotten any worse than this’’
