My best friend

I knew my best friend in high school. I do did not like her. I am a shy and traditional person, but she is a confident and too open person, always walking like a cock.**
It's a destiny, we were arranged to live in the same dormitory. She always followed me and talked to me. I retorted her with a bad temper. We have kept the relationship going for 19 years, and we broke up 3 times and became reconciled 3 times.
We are two different kinds of person people, but I am sure we are the best possible friends for each other. When one of us is in low station down, the another one is always there.
Think god for giving me a friend like that.

**: I'm not sure exactly what you mean by "cock" here. That word has multiple meanings, some more negative than others. In any case, we don't usually use this to describe  some one's way of walking, but i think it is actually quite good. Just be aware that it has multiple meanings and could be offensive in some situations.

Good work!

My best friend

I knew my best friend in high shool. We have very different personalities. ( I am not like her.) I am a shy and traditional person while she is a very confident and open-minded person who always walks like a proud rooster.
It's destiny that we were arranged to live in a dormitory. She always followed me and talked to me, but I retorted her with bad temper. We have kept our relationships for 19 years. We broke up three times and reconciled three times.
We are two different kinds of persons, but I am sure we are best friends. When one of us is in low spirits, the other one is always there.
Thank god for giving me a friend like that.

"Walking like a cock" ... do you mean strutting about?

I knew my best friend in high school. I do (am?) not like her. I am a shy and traditional person, but she is a confident too open person who is too open, always walking like a cock coq (chicken? this simile doesn't really work in English).
It's a destiny, we were arranged to live in a dormitory. She always followed me, talked to me, I retorted her with a  bad temper. We have kept the relationship for 19 years (We have known each other for 19 years?), and we broke up 3 times (our friendship fell apart 3 times) and became reconciled 3 times.
We are two different kinds of person people, but I am sure we are best friends for each other. When one of us is in low station (in a bad situation/feeling low), the another one is always there.
Think thank god for giving me a friend like that.
