Is this proper grammer and punctuation. Ques.describe the lives of the old people who arementioned inthis song

The line in the first verse would correctly say, "Still don't know what for, doesn't matter anymore", however the timing may not fit for you that way, and a little leeway could be given there, so it would still work the way you have it. There are a few other places where you used slang, like "Ya know" instead of "you know" and that's fine. The line that says "she sits and stares through at back door screen" should read "the back door screen" or "that back door screen". Unfortunately you didn't have room for the rest of the song. It sounds like a good one, a song that makes you feel their loneliness. Did you write this for a contest, or is it an established song somewhere? Good luck!
