"Presents"

Why is it that when we buy something online or from a catalog, while we wait for it to come, it feels like we are getting a present???? i ordered a couple of shirts for me and some shirts and shorts for nicholas from old navy as well as 2 new babies/lovies for nicholas.....nothing fancy, just simple stuff, but when i see the ups guy or the fedex truck or the mail truck go by my office window, i get excited...it is always like that when i order something, i guess it is the anticipation of "finally" getting something you have paid for already and being able to use it....most of the time from the time you place the order till you receive the goods, it is no more than 5 days or so, but it always feels like an eternity....i know it is silly thinking, but i just love "presents"
