I don't know how to be the best friend, but I do know how to be the true friend

for some reason, I start being afar id that others might introduce me as her friend.
not because the way others see her, but because the way others might reflection her on me.
I was true and thoughtful, but also being wise of choosing friends. she is the kind that I always try to avoid from. but I thought she might be the chellgeg that Him sends to me.
I wondered the reasom we become frineds. Is she just someone I know now? or we ever truely be friends?
at this moment, I'm afarid how she will react if she notice that she is not my best but just someone I thought I know only. I'm also afarid when the day comes into our lives, yet I won't even care how she will react anymore.
So I chose to be true. maybe not true for any kind or interaction, but at least being true to her when I need to be.

Are you my true friend? Will you ask me to walk away too?
