Dear Sir Sleeping on the Loading Dock,
I know I am oft quite callous in my approach to the residentially-challenged individuals; however, I would like to state that I am, in fact, quite empathetic to your plight. I am very fortunate to enjoy the life that I do and that I have the skill set, sanity and knowledge to provide for it.
However, I would be remiss if I did not bring attention to the fact that sleeping with a plastic sheet over your head just screams "Future Darwin Award Winner."
I am on edge that I will be reading about your accidental asphyxiation one of these mornings. Please heed my concern.
