In reality, we don't have the same father, exactly a different father per childnone of us do, but I considerate them like my reals siblings.

We have a fiftheen year age gap.

I realonly realized she was my sister when I becameonce she made me an aunt.

Before, I thought she was a friend of my mother, because she lives onff her father.

She was an apprentice hairdresser, so I only seeaw her whilen she came to cut my hairine or mother's hair.

She is one of my favorite people, with my two nephews (I don't know the word for girlfemale version, in french it's : nièce).

English sometimes borrows accents but the english 'niece' doesn't

She haves a strong character, and even a little bit choleric, but she is a loyal person, she is kind and I can trust her.

Our mother passed away last week, and we help mutually decided to help each other out.

It's a case of the middle child, but in this case it seems it's not the easier placst one to be.

I love him, but he leaveft the house when I was eleven years old, and we didn't speak during a lot offor many years.

He cut the contact with my mother and he never speak againoke with her again.

He contacted me again when I was eighteen, but we were like strangers.

We don't have sameimilar values or objectifves onf life.

Today, I try to keepmaintain the contact, and I call him sometimes.

My Brother and sSister

Capitalization aside, this is all fine. "My Siblings" would be equivalent, and shorter, should you prefer it.

In realityThe truth is, we all don't have the same father, exactly a—that is to say, we each have different father per child, s—but I considerate them like they are my reals siblings.

There is a lot of annoying comments these days about how using em dashes (—) makes your writing look like it was done by AI, but the truth is, that's how you separate out related, but incidental clauses. (A pair of parentheses would have also worked, but the em dash is more appropriate here.)

T(I'm the favorite child, you know.)

A bit cheeky to say, but that is bias on my part. And yes, let's use parentheses here, as opposed to using em dashes from earlier.

We have a fiftheen-year age gap.

The fixed version is fine; alternatively, you could have said "She is older than me by fifteen years." which is what one would more commonly write.

I realonly realized that she was my sister when I became an aunt.

Before, I thought that she was just a friend of my mother, because she live ond with her father.

She was an apprentice hairdresser, so I only seeaw her whenever she came to cut my hair or my mother's hair.

Now, we are very, very close.

She is one of my favorite people, along with my two niephews (I don't know the word for girl, in french it's : nièce)s.

I am assuming both of your older sister's children are girls; thus, "nieces" (a word that the English language indeed borrowed from the French, among many others). ;) Otherwise, it would have been "with my niece and my nephew" if only one of them is a girl.

She haves a strong character, and is a little bit choleric, but. However, she is a loyal and kind person, kind and I can trust her.

Instead of "strong", "forceful" is what I would have used if I were you, but this is okay.

Our mother passed away last week, and we help mutuallyed each other.

ItHe's the middle child, and it seems it's not the easier placest position to be in.

I was married with two little boys, but hewhile he got divorced this year.

Your "was married" threw me off, but this is indeed correct if you are no longer currently in a relationship with the father of your two boys. Otherwise it ought to be "am married".

I love him, but he leaveft the house when I was eleven years old, and we didn't speak during a lot ofwith each other for many years.

He had cut thehis contact with my mother and he never speakoke again with her.

He contacted me again when I was eighteen, but we were like strangers.

We don't have the same values or objectifves oin life.

Tohese days, I try to keep the contactin touch with him, and I call him sometimes.

In reality, we don't have the same father, exactly. Each of us has a different father per child, but I considerate them like my reals, but I think of them as full siblings.

TOf course, that makes me the favorite child, you know.!

I modified this to get across a more humorous tone!

The oldest is mMy sister, Aurélia, is the oldest.

What you wrote is grammatically correct, but I usually hear the name specified first in a sentence.

We have a fiftheen-year age gap.

I would write this as, “She is fifteen years older than me.”

Now, we are very very close.

She is one of my favorite people, along with my two nephews (I don't know the word for girl,; in fFrench it's : “nièce”).

The word is “niece” in English too. We just omit the accent!

She haves a strong character, andpersonality, a little bit choleric, but she is a loyal person, kind andand kind person, someone I can trust her.

The word “choleric” sounds very literary in English. I might say “irritable” or “touchy.”
