I think you have a good start! I like the first line especially. However, I think the next one needs some work (besides the spelling, which I corrected): "It sounds like a friendship of true." That doesn't really make any sense, and even though you are being metaphorical, there needs to be enough truth in the words to make your reader relate to what you are saying. Try this line again; perhaps it could sound like some type of music. Or the ringing of a bell. Does the poem have to contain rhyme? If so, perhaps "The sound of a dove's quiet coo."
I hope this helps!
