Over the course of the past few weeks, a mystery has plagued my home. While normally we have more than enough drinking glasses to go around, lately we have all come up just a little short when reaching for a cup. What has caused these strange disappearances? Perhaps the dishwasher eats them, or drifters passing through take them for their collections... but alas. Today I discovered the true source....in my bedroom. Yes; there were four half-empty water glasses strategically placed throughout my room.
