My facebook friend

I have a facebook friend name Sierra Last name I rather not say
Sierra hit me up on facebook, "Anthony are you ok?"
I know a lot of things about Sierra like one she don't like me
Which got me thinking, "Why the hell did Sierra just write me?"
I replied back to her "I'm good I can't complain."
She said I heard you were crying I said no I just came in from the rain
She said its cool to talk, your emotions are safe with me
I said I don't trust you these feeling are going to stay with me
She said no Trust? I thought we were friends
I replied LOL when did that relationship begin
Ok Sierra heres a test, How often do we text get your phone take a look
The answer should be we don't thats why our friend only exist on the book
