I can completely understand...many, many years ago, while in college, I worked nights so was catching a few winks during the afternoon between classes. I also sleep sans clothes. So, there I was, enjoying my afternoon siesta when I hear knocking at my apartment door. Not expecting anyone, nor really wanting to get out of bed, I ignored it. Unfortunately, whoever it was, kept knocking and knocking. At this point I was awake enough to be upset that someone was keeping me from my nap and awake enough to hear someone fiddling with the lock and then the door opening. Knowing that no one had keys to my place, I immediately jumped out of bed, grabbed my gun (Colt Officer's) and stepped into the living room. Needless to say, the plumber, who was there to replace the shower head to a low-flow model (and whom the manager had forgotten to tell me about) was quite surprised. I am not sure what scared him more, the gun or the nakedness....I never did get that low-flow shower head installed.
