Many years ago, while I was driving into work, an older couple in another car pulled up along side of me and started blowing their horn and waving at me. I had no clue what they wanted so I just sped up and continued down the road. They did this 2 or three times. The last time they sped by me and pulled into the breakdown lane, still waving and blowing their horn. I pulled in behind them to find out what was going on. It seems that I looked like, and was driving the same car as, their son. It actually took me almost 5 minutes to convince them that I was NOT their son.
