Difference between UPS and the post office?

Question

okay... one time a package was on my door step b/c the post office put it there but it wasnt for me. So the nest day I saw a brown ups truck in front of my house and I yelled for him to come over and he did and I told him about the package if he could take it. He said no that is was the post office that droped it off? So that is the difference?

Answer 1

One UPS is the United Parcel Service (a private company) and the other is the USPS - United States Post Office (the one run by the government).

Hope this helps.
