I went on vacation recently, leaving a certain roommate in charge of feeding my hamsters. In retrospect I should not have entrusted him with this task. I arrived home to find them dead in their cages because he'd forgotten about them. Because of this, I've had him evicted.
I will be holding off on buying new hamsters for a while, to mourn the loss of George and Scott. They were very old at least, and lived full lives. Still, it's an infuriatingly senseless way for them to die.
