Very often when I am walking on the street or am in shul or at some event, total strangers walk over to me and either ask me am I Yankel Finkelstein or Shloima Cohen or whoever and sometimes people just start talking to me about something I have no idea about, he having assumed I was some acquantance of his.
I’m sure this happens to everyone on infrequent occasion. But I experiance this phenominon quite frequently. It is true I have a very “common” Jewish face, but could that really explain it all?
