I can’t remember a time I mailed either a letter or package that didn’t get to it’s intended location.
Hahaha. Tell us you aren't a productive person without telling us you aren't a productive person. Anyone who has the unfortunate displeasure of dealing with the USPS knows your mail is as likely to get lost as it is to arrive. Maybe they deliver your once a year Christmas card to wherever, but for anyone that has to send and receive alot; they're w disaster.
Ups, FedEx, and email didn't all come about because the mail was so swift and efficient.
