I have the privilege of working from home sometimes (obviously not when I'm on the road) and those who know me well are aware that I speak out vehemently regarding mobile phone ringtones.  In particular, I find them often irritatingly loud and obnoxious.  Well, I may have second thoughts.  I am working at home today, with my phone (set to vibrate) laying to my right on the desk.  I heard the vibrations and reached for my phone, only to realize that it was not my phone, but rather a guy weedwhacking two houses down.  I feel silly.
