your best female friend
You are your own best friend.
I will be your best friend.
Soy tu mejor amiga en todo el mundo.
I'm your best friend in the whole world.
Hiciste mal en mentirle a tu mejor amiga sobre eso.
You were wrong to lie to your best friend about that.
Se supone que soy tu mejor amiga y me dejas fuera.
I'm supposed to be your best friend and you leave me out.
