Where have I gone wrong

I may not be important, 

Because am like a grass growing in your farm land

So all you need do is to *choke me off and cast into a burning flame;* 

My presence is now invisible that you can't sense it nor feel it, *am now the uninvited wind;* 

Once a friend they say' is always a friend, yet in you I can't see the always: and a lost friendship i wept for

If nature that brought us together have dropped a rain and sun to dry it up before reaching my Palm's it would have been a mystery, but the rain dropped in my Palm's and spilt out unnoticed to the floor were the sun lowered it's hot flame to dry it up. 

***Friend where have I go wrong?***
