There are many types of collections. Some are formed by purposefully collecting certain objects, such as stamps or coins. However, some collections are only a byproduct of an obsession, a quirk of mind. For example, Paul Brockmann got into the habit of buying his girlfriend and later his wife a dress every time they went ballroom dancing. It might seem excessive to some, but it was his way of showing his affection. Overtime, this collection grew to be enormous, counting 55,000 dresses in total. Basic math tells us that either they went ballroom dancing three times per day for every day of their lives, or he bought them in huge bundles every time.
