Questions about example sentences with, and the definition and usage of "Yesterday"

A: It was a new expression for me too. Just learned it. Thank you for the post.

A: 「久しぶりっていうことじゃないけど、なんかマジで会いたかったよ」の意味が通じます。

Rephrasing: "I missed you, despite the fact that it hasn't even been more than a few days since I last saw you." The '??' in the original statement is actually just a rhetorical question.

A: Stop lecturing me about STDs mom! This is the 21st century and I wasn't born yesterday!

Oh really? Gravity makes things fall down???!!! GEE, NO WAY! You know Tom, I'm not an idiot!! I wasn't born yesterday!

I wasn't born yesterday. I know that the world is a harsh and cruel place. Only the strong survive.

"I wasn't born yesterday." is used mostly as a sarcastic bitter expression since stating such an obvious fact usually expresses strong disapproval with the thoughts/words of the other person. At the same time, it mocks the other person since the fact of "not being born yesterday" is obvious. This expression can be used in a "playful" way around certain people or it can be rude and mocking. No matter it's intent it always is sarcastic in nature and therefore, I highly wouldn't recommend it's usage.

A: The difference is very small.

"Do as you did yesterday" means act the same way you did yesterday, your demeanor, performance etc.

"Do what you did yesterday" could mean the same, but the speaker could also be asking you to repeat the exact same actions as yesterday, like get out of bed, brush your teeth, make a black coffee etc. So, it is more specifically referring to your actions.

However, this is just my personal understanding. It's possible other native speakers would read them as exactly the same!

A: "It rained yesterday" is a simple statement of fact. "It was rainy yesterday." describes the weather during the previous day.

A: The first one is correct, the second is not.
"Why were you angry yesterday?" ✅

A: It’s just a matter of how the words are placed, they all mean the same thing.

“Yesterday was my birthday.”
Yesterday is the topic of the sentence.

“My birthday was yesterday.”
While in the 3rd sentence, the birthday is the topic of the sentence.

“It was my birthday yesterday.”
‘It’ acts as a placeholder noun and is the topic.

Even though they all mean the same thing, placing one word first over the other emphasizes it. But that’s more of a writing style technique, not something to be worried about for everyday speech.

A: First, it is a rule that is almost completely ignored. But is is for both questions and statements.

I don't know where the dog is.
Nobody will tell me what's happening!
My father deals with a lot of issues.

A: Yesterday I was so drunk. I’m still trying to recover from this hangover.

A: I was sick yesterday.

A: You say "How was your day yesterday?" or "How were you yesterday?"

How about; I didn’t want to do anything yesterday and just stayed in bed.

A:

1. We stopped by there because we were close. We weren't even planning to go there yesterday. But I think it's still worth TRYING THE other two locations if I have a chance, since Law donuts have been hyped up AMONG Japanese lately.

* The phrase is "worth xing" (worth trying). There is a natural pause after "have a chance" and before "since", so a comma there is best.

2. There is another fitting room on the third floor. ONE of the roomS THERE is available. IN OTHER WORDS, she's saying that this floor's fitting ROOM is full so you can go to the third floor instead (IF YOU LIKE).

* Is this a store clerk speaking to a customer? When speaking to a stranger or acquaintance, avoid speaking for another (third) person, this can come across as arrogant.

例: A: "Do you know where the fitting room is?" B: "It's on the third floor." A: "What?" C: "She said it's on the third floor". <-- Avoid

"If you like" is a polite way to offer an option without pressuring someone to accept it.

"So"

A. Commas come before "so" when used in the middle of a sentence. B. "So" should be used only once in a sentence. C. In American English, starting a sentence with "so" as a filler word has become more common recently and is associated with young people. It can sometimes be seen as annoying or rude, you should be aware of this: https://english.stackexchange.com/questions/43273/sentences-beginning-with-so

3. I saw a someone standing in line for the donuts store for 2 hours on Instagram. (!)

5. My friend threw a party and we celebrated her daughter's birthday. It was THE first time l've participated in an international party. I assumed it was gonna be a small party since my friend said there'd be a few people coming, but IT (パーティーと言う事が) ended up BEING almost 20 people.

"expected yyy, but ended up being xxx" - expected yyy, got xxx.

Use either "my first time xing" or "the first time I xed" (they are set phrases).
