Sometimes we hate them. Sometimes we love them. I don't know what to make of them either. It seems that their service standard is well....not standard at all. Anyway, this is the United States Postal Service or USPS for short. Most of our mails goes through them and lets be honest, they do quite a good job when it comes to delivering the regular mail. And when I was young, seeing the mailman come is an event in itself. Thus I have to admit, I wanted to be a postman. But then I realize that being a postman probably suck and can be dangerous, especially when visiting houses with dogs and all. They also provide courier and parcel delivery services like Fedex and DHL. If I am not wrong, they are indeed major competitors in this field. Oh you should read up on the history of the USPS, pretty interesting stuff.
