I've heard that the word "normal" could be a sensitive word depends on the context. Why is that?

I've heard that the word "normal" could be a sensitive word depends on the context. Why is that?

The word "normal" implies that there's a certain way one must look and act to fit in. But then, that doesn't consider people who may not fit these standards of "normal" and are then put to the side or seen as lesser! Such as people with disabilities. What someone views as "normal" can be very subjective, so I guess it depends on the contexts you use it in and why. Ex: A normal day for me starts with waking up at seven am and going for a jog! Ex: I used to wish I looked "normal". But then I realized I like the way I look.

When can I use the expression "you see"?

We use "you see" when we hope someone else will understand what we are saying or asking. It is a way of encouraging them to listen and understand you. Ex: You see, it's much better if you have dessert after dinner. Ex: You see, I didn't take your t-shirt.

What's the main difference between a "firm," "company," "enterprise," and a "corporation?" Or are they all interchangeable?

This is a good question, and a bit difficult to answer. They are synonyms for each other, but some are more formal or legal in meaning. A company, a corporation, a firm and an enterprise are all businesses. "Company" is the most general, common term used to describe businesses. Note that not all companies are for profit! Ex: I started my own little company selling custom-made t-shirts. Ex: I work in the company that my father started. Corporations can be understood as very large companies, or a group of companies. In a legal sense, a company can only be considered a corporation (Co. or Incorporated, Inc.) if it has gone through the process of incorporation. Ex: I work for the pharmaceutical business of a large corporation. Ex: Amazon is one of the biggest corporations in the world. Meanwhile, a firm is a business that is owned by a core group of individuals, and is often comprised of senior group of partners that provide services. For example, law firms or accounting firms. Ex: I am an accountant at an accounting firm. Ex: I am interning at a small firm for family law. Lastly, an enterprise is a business run by an entrepreneur (or entrepreneurs). It may be more diverse in nature, and is always intended to create profit. Ex: I proposed the creation of a new enterprise in the supply chain industry. Ex: My plan is to launch my personal enterprise within the next five years.
