That was beautiful. Thank you for that.

To the original poster: I am similarly thin-skinned in these situations and can completely relate to your frustration. Try to see the exchange from the other person's perspective; there are a thousand things you don't know about that could be distracting them from a timely reply. If their failure to respond hurts you, then stop sending them messages. Correspond only with those who recognize and respect your need for a response.
