We know this is a memory , so you don’t have to say I remembered

I remembered I had a best friend named Wang in elementary school.

His mother was beautiful and filmed for a local toothpaste brand, s. She once invited me to have a lunch at their house,. I hadve a strong memory onf the delightful dumpling ons (she served) that day.

We studied at school, played games after class, and sometimes chipped in pooled our money to buy snacks.

"Chipped in money" would be if someone else were already buying snacks, and you contributed some money. "Pooled our money" means the two of you decided to buy snacks together.

That's a memory like an elephantcherished memory, a time without anxiety.

If we say someone "has a memory like an elephant," we mean they remember things for a long time; they never forget.

I thought of him as my best friend.

But about 30 years later, It was in 2014, I ran into him...

Merge this with the next sentence.

I met him in the opening ceremony of grade one and occasionally foundran into him at my daughter's first grade convocation ceremony and happened to find that his daughter and my daughter were in athe same classroom.

I called his name excitedly, but he had forgotten my name and finalonly remembered me after I said out my name.

I felt a sense of failure and make a badcame to an unpleasant conclusion: I treated him as my best friend, but he didn't think sofeel the same way.

Maybe he has a very bad memory, or was having a bad day and then felt very embarrassed because he couldn't remember your name. Or maybe your appearance had changed so much that he couldn't recognize you.

Actuallyfter that, we didn't chat or phone to each other (face to face ev), not even when our daughters graduated from school.

"Face to face" means "so that you can see each other's faces." It doesn't really make sense to me here, unless maybe you mean a video chat.
