Plates and bowls have nothing to worry about

How do I manage to break every interesting coffee mug that I buy with my own money, but the stupid ugly clear glass Bailey's cups that were here when I moved in remain intact?
What's even sadder is that they were probably freebies included with a purchase by the previous tenant of some over-sized bottle of that over-sweet over-creamy crappy excuse for an adult beverage.
It is truly a wonder that my coffee press has yet to meet it's demise at the hands of my clumsiness, paired with my poorly designed under-the-counter storage space.
Worst. Idea. Ever.
