Your first memory of one friend

I met my best friend, when I was 10 year old.
We went to the same school, but she was in sixth grade and I was in fifth.
I met her and her friends on the break.
And I felt it within me:
"I want to be friends with her."
So I went up to them and said:
"Hey, can I join you? "
Smile.

The rest of this tale is that 41 years later we are still best friends.
We are acquainted with each other's secrets.
We are still each other's backs when needed.
We are friends. whose friendship was created already before we were born.
Me and my friend Dadi.
