Get idiomatic

An expression, word, or phrase usually presumed to be figures of speech contradicting the principle of compositionality. When a speaker uses an idiom, the listener might mistake its actual meaning, if he or she has not heard this figure of speech before. It can also mean an expression whose meaning is not predictable from the usual meanings of its constituent elements, as kick the bucket  or hang one's head,  or from the general grammatical rules of a language, as the table round for the round table,  and that is not a constituent of a larger expression of like characteristics.

Sharon: What do you do?
Matilda: I am a Freelancer
Sharon: That’s great. R u in touch with anyone from college
Matilda: Nope….
Sharon: I miss college. It was so much fun. I still remember that guy you had a crush on. He was as cute as a bug’s ear that suffered from Lygophobia and always had this miserable look on his face.
Matilda:That son of a Gun was very cute. In fact all the girls use to drool over him. Do u remember that snooty little thing on the day we had a farewell party. She was powdered and curled in radiant pink satin, with waistcoat bedizened with gems of pink paste and a hat blazing with 5,000 metallic beads.
Sharon: I miss college as a hell. Those were the halcyon days. What else?
Matilda: I want to do an MBA in Advertising and I am planning to give the CAT this year, but the only section I am apprehensive about is the math section. Math is my Achilles heel. At times it is all Greek to me.
Sharon: Oh! So why don’t u join a coaching class. They prepare students for these tests.
Matilda: Well I've got to get this report finished by tomorrow so I guess I'll be burning the midnight oil tonight. I am so fagged out.
Sharon: I can imagine your plight. I still think you should wait for some time and appear for the CAT in November. You will have time to study.
Matilda: That makes sense.
Sharon: Hmmmm…  Let’s catch a flick next weekend
Matilda: Cool!!!

I am fed up. My team manager is never satisfied. Every time I achieve my targets, he raises the bar and lectures me on what to improve upon. I want to do my MBA in operations and don’t even get time to study for CET, as I am so busy. I guess am going to quit because CET is just around the corner. The only section I am apprehensive about is the math section. Math is my Achilles heel.

Michelle: Oh, it must be quite difficult for you then. You need to de-stress, so that you don’t get burned out in the process.

Matilda: Hmmm.You are right. My manager thinks selling is a piece of cake. I mean I like what I am doing, but he just doesn’t understand and now he’s twisting my arm to cut a deal with LTP by tomorrow. But even if I manage that, I know we don’t have the bandwidth to satisfy their requirements so soon.

Michelle: I can imagine your plight. I know what you are going through, but I still think you should wait for some time and appear for the CAT in November. You will have time to study and you can join IMS coaching classes that prepare students for these tests.

Matilda: I think that makes sense. I miss college. Those were the best days of my life.

Michelle: Yeah right. You had a major crush on him and so did I. In fact all the girls use to drool over him. He was so tiny and everyone used to call him lilliputian.  He was cute as a bug’s ear.

Matilda: I agree. I am so fagged out. I have been so busy with work. I have a long day tomorrow. Lets catch a flick next Saturday.

Michelle: Cool!
