Of course, some families do not wrap their gifts, and others do not put stockings up as all. Many families leave their gifts unopened, either beneath the tree or on the mantle with the stockings, so that the children may see what Santa brought them as soon as they come downstairs. This is called a "Santa Packed Bag" or a "Santa Closet". The tradition of wrapping presents comes from the Catholic Church's practice of adorning trees for Christmas. They would wrap presents for poor people who could not afford gifts themselves. The practice spread after it was adopted by secular merchants as part of their holiday season celebrations. Today, most families continue this tradition, though they may use paper instead of ribbon or not at all. Some prefer to keep their gifts secret until Christmas Day when they can be opened in front of a crowd of friends and family. Others may send their kids to bed with their stockings hanging by the fire and let them wake up to find a gift in their stocking. Wrapping gifts helps children learn about responsibility. It teaches them that things should be treated with care because they are worth money or valuable items. It also teaches them about gratitude - if you don't have anything nice to say then don't say anything at all! Finally, wrapping gifts is a time-consuming activity that requires patience and attention to detail.
