I had the same thing happen to me, back when I was young and traveled all the time , normally two weeks at a time. I walked into the auto parts store to only be met by the ashen looks of the guy behind the counter. A Bob Brown and drowned in the lake fishing a few weeks ago and everyone assumed it was me. We about the same age and lived in the same county. He looked at me and said "I told everyone it was you." He said he was glad it wasn't, but felt bad about telling other customers it was I who had drowned.
It was a wake up call for me as I drove through town on my way home. Ilive in a small town where everyone pretty much knows everyone else. The town had not changed, everything went on as normal, The town as far as some residents were concerned... I was dead. In reality I realized I did not matter, people got by just fine without me. After that I made a point of making a difference in people's lives. I became more interested in them than myself, I got involved in local politics, the ministry and became active in a few social groups. I made a point making sure that someone else came first, that by giving them a hand when they needed it...that the day the hand disappeared that it would be missed. While it sounds really noble it is in fact selfish. I did come to realize that thinking of the other guy first does make a difference. I did find that that I can change things. The Bob Brown that died in the lake that day took a little piece of me with him, and for that I am thankful.
