ShibaiDakine,

Your post is not only highly patronizing, but insulting as well.  If you read carefully and can appreciate the context, you will note I made mention of the USPS Informed Delivery option.  It is an online service, therefore even most 7th graders would have implicitly known the writer is computer literate.

If reading my post somehow upset you in a way that provoked your reply, well, to be frank, nobody promised you seeing the truth wouldn't hurt sometimes.  In your own personal life, I take it you have never had your mail lost?  But then, if the lost item was something mailed to you as bulk rate or other than first class, how would you ever know?

With that, enjoy the rest of your day.
