Well, Rose, I would care, for one. I also completely understand where it is you're coming from.
Our children grow up, eventually "leave the nest", and we, as their parents, are virtually forgotten, unless they want something from us. They get busy and so wrapped up in their own lives, it rarely occurs to them that their parents miss them dearly and would love to hear from them once in awhile.
Your touching, poignant, poetic proclamation portraying one parents pain is well written, well rhymed, and to the point.
But never believe for one second that no one would care. That just isn't so.
