A horrible kitchen discovery

This morning the overhead light in my kitchen was repaired. Now, a little background on this. Seven months ago, when we officially came into possession of the condo, the light was quite functional. Six and a half months ago, on the day that we finished moving in, the light stopped working. After a long and tedious process, the light finally was fixed (with a repair that took all of ten minutes), and the kitchen was filled with its fluorescent glow. I soon had to turn the light off, as it was showing the kitchen for what it truly is: really fucking dirty.
