I was reading a news article today about two brothers who met by chance after 30 some odd years. One recognized the US east coast accent of the other and started listing off names from a particular town to see if they knew anyone in common when they realized they were brothers who were separated at a very young age. Here is a link to the story
So keep your accent - you never know when your world will collide with someone from your past.
And wear your sun screen.
