If you can, try to remember to capitalise the first letter in your sentences. I know many English speakers forget this (or choose to use only lower case letters because they want to appear more casual), but capitalising the first letters of sentences makes them easier to read. Thanks! 👍

Not sure what you meant here

tThat makalso guarantees a great future and properties in my familyfor my family. No matter what happens, we are resilient. That also guarantees a great future for my family. No matter what happens, we are resilient.

I think I understand how you are trying to describe the relationship in your family as having positive “properties” (characteristics is a little bit more appropriate a word btw, but still feels too “detached”)… I’m not sure how to express this idea, and “properties” is a fairly cold or “clinical”/“scientific” word. I hope that helps and you like my suggestion?

even though I have argued with my older brother and had ridiculous fights in the past, we gotrew a bit older and we got along with each other. even though I have argued with my older brother and had ridiculous fights in the past, we grew a bit older and we got along with each other.

It’s totally optional to add “in the past” or “grew” but sometimes these extra words can help readability. They are like “signposts”, for emphasis.

Although I used to be close to my brother before his migration, now I amove, I am now close to my mom. Although I used to be close to my brother before his move, I am now close to my mom.

because ofwe sharinged the same ideas about many things and issues, we got close. because we shared the same ideas about many things and issues, we got close.

"We got close because we had many things in common" sounds better

because ofSince we sharinge the same ideas about many things and issues, we gotbecame closer. Since we share the same ideas about many things and issues, we became closer.

“Because of sharing” is a bit clunky here, I’m sorry I can’t explain… My grammar is mostly only intuitive (by feeling not logic). I replaced “got close” with “became closer” because it is a bit more natural.
